List of Tamagotchi releases
This is a list of every Tamagotchi virtual pet ever released, in chronological order.
Original Pets (1996–1998)
Tamagotchi Generation One
The original Tamagotchi was a virtual pet created in Japan by Akihiro Yokoi of WiZ Co. Ltd., and Aki Maita of Bandai Co. Ltd. It was released in Japan in 1996, then in America and Europe in 1997. It had one baby character, one toddler character, two teen characters, and seven adult characters, for a total of 11 characters. One of the adult characters was a "secret" character, which could eventually appear from one of the other adult characters if given a certain level of care.
In America, the Tamagotchi was available in many different shell colors and patterns. Here are a some examples:
- Clear blue with yellow, white with blue, yellow with orange, green lime with yellow, red-pink with yellow, purple with pink.
- Green clear with blue, warm orange with yellow, dark blue with bright pink, pink with green, semi-pale blue with purple, dark purple with blue.
- All green clear, white with black.
- Clear purple with white, purple with white pastels, yellow with purple pale, green with milk white, white with red, and red with white and black.
Tamagotchi Generation Two
The Tamagotchi Generation Two is very similar to Generation One in terms of programming. The two "generations" have different characters and a different game in each, and a number of other minor differences, such as small differences in the Meal and Snack options,the background of the Tamagotchi and in the animation that is shown at the end of a Tamagotchi's life.Also, the packaging has several differences.
Tamagotchi Angel (Tenshitch no Tamagotch)
The Tenshitchi no Tamagotchi was released in Japan in August 1997 with three different designs, and a later English version, the Tamagotchi Angel, was released in America and Europe with four designs.
Mesutchi and Osutchi
The Mesutchi and Osutchi were released in December of 1997 in Japan only. They feature interlocking mating using the same interlocking technology that Digimon used to connect, in which the tops of each Tamagotchi would lock together so that they could communicate with each other. When a Mesutchi and Osutchi connect in the adult stage, their mating may result to a child.
Both Mesutchi and Osutchi feature 31 characters each. Four different generations, or TMPs, of Tamagotchi are available, but only the first one grows in a way that is affected by caretaking skills; the other three are linear. If the caretaker is not responsible in their care for their Mesutchi or Osutchi, the Tamagotchi will become an adult character uninterested in love. If the caretaker feeds the Tamagotchi too much food and it and it becomes overweight, it will turn into a "Debutchi" which takes up the whole screen. In this state, the user can not do anything with the Mesutchi or Osutchi except play the game and check health status. The caretaker then has to lower the weight of the Tamagotchi by playing the game before normal functions may resume.
Tamagotchi Garden (Mori de Hakken! Tamagotch)
The Mori de Hakken! Tamagotch, commonly referred to as the Mori no Tamagotch, was released in February 1998 with four different designs. It was scheduled for release in America as "Tamagotchi Garden" but was not released. This Tamagotchi introduced the "predator" function also used in the later Umi de Hakken! Tamagotch (Tamagotchi Ocean). Occasionally a predator attacks, and the care taker has to use the sound-sensitive functions introduced in the Angelgotchi by shouting or tapping at the screen to frighten away the attacker. If the attack is a success, the Tamagotchi may become seriously injured or even die.
Another notable function of the Mori no Tamagotchi is the teenager phase: It is replaced by a cocoon, which remains for 24 hours, during which time the care taker controls a temperature dial. If the environment is mostly humid, the Tamagotchi will change into the "warmer" creature for that quality of care, and vice versa for cold weather.
There are two types of eggs that can be selected to hatch in this Tamagotchi. The white egg is more like a traditional Tamagotchi, where it changes based on how it is cared for. The spotted egg always changes into "Kabutchi", the stag beetle, where the goal is to make your pet as large as possible (a "length" meter is displayed to track this).
Tamagotchi Ocean (Umi de Hakken! Tamagotch)
The Umi de Hakken! Tamagotch (Tamagotchi Ocean in America), often referred to as the Umi no Tamagotch, was released in March 1998 in Japan in four different colors. It was also released in the United States in 1998 in four colors (though they were different from the Japan colors). This is known as one of the most difficult Tamagotchi to raise, needing near-constant attention. This Tamagotchi includes the "predator" function also used in the Mori no Tamagotch. Occasionally, a polar bear will attack while the Tamagotchi rests. Therefore, the caretaker has to use the sound-sensitive functions by tapping on the unit or shouting to scare away the predator. Like in Mori no Tamagotch, if the attack is successful, the Tamagotchi may become very ill and may even die. The Tamagotchi includes a "water quality" meter in the status screen. Flushing the screen makes the screen "cleaner," but if all four skulls on the meter are filled, the water becomes "murky" and it has to be flushed in order to view the Tamagotchi again. This secondary use for the cleaning function is not used in any other Tamagotchi. The water that the tamagotchi lives in is soda water.
The Japanese versions of this tamagotchi maybe easier to find but however the American version is harder to find and a lot more expensive, they are very rare.
Devilutch no Tamagotch (Tamagotchi Devil)
The Devilutch no Tamagotch, often referred to as the Devilgotchi, was released in Japan only in September 1998 in four different colors for ¥2079. Some aspects of the care are similar to the Tenshitchi. Unlike the Angelgotchi characters, who are eager and do good deeds for the caretaker, the Devilgotchi characters are naughty and play tricks.
The Devilgotchi was later remade for cell phones, and distributed in Europe as the Tamagotchi Monster.
The Yasashii Tamagotch was released in Japan in October 1998 in three colors. Acting as an "Easy Tamagotchi", it has slightly different evolutions than the first set of Tamagotchi toys, and also features a larger case. In the place of icons, backlit buttons were used, and the number of buttons at the bottom of the case were reduced to two: Select and Cancel. Today, it is one of the rarest Tamagotchi that exists. It will almost always sell for at least $100 (in used condition) in both retail and auction sites, and has sold for as much as $400 mint in box. 
The Santaclautch is a Santa Claus and Christmas-themed Tamagotchi which was released in December 1998 in Japan only. The Santaclautchi character does not evolve, but can be changed by means of equipping different items. The goal of the caretaker is to prepare Santaclautchi to go to each Tamagotchi's house and give presents. If Santaclautchi does not do this in time, the Tamagotchi gets mad, Santaclautchi gets upset, and the care taker has to start over.
The character which the caretaker would have to take care of is a winged beast called Mothra Tamagotch. It was released in Japan in December 1997, to promote the Rebirth of Mothra movies. Mothra would hatch as the Larval version of the movie character, and evolve depending on care into one of its super powered forms, such as Rainbow Mothra. The programming is similar to the Morino Tamagotchi.  Godzilla was also a hidden character.
Genjitchi is a caveman-themed virtual pet released in 1997.
Modern Releases Available Worldwide (2004–2008)
The Tamagotchi Connection (known as the Tamagotchi Plus in Japan and the Tamagotchi Connexion in Europe) was the first modern Tamagotchi released since 1998. The Japanese edition was released on March 20, 2004. The English-language version was released in North America on August 15, 2004.
It allows players to connect via infrared (known as Tamacom) to other players systems and become friends, get married, and produce offspring. The English edition also introduced the "pause" option, which stops growth but continues time within the Tamagotchi unit, until the caretaker resumes play.
Tamagotchi Connection Version 5
The Tamagotchi Connection Version 5 is the current Tamagotchi in the Tamagotchi Connection Series, as of 2008. The Japanese equivalent is known as the Family Iro Iro! Tamagotchi Plus. Its motto, according to the package, is "We are Familitchi!" as in the song "We Are Family" by Sister Sledge, and according to Tamatown the motto is "More Family, More Fun!" The V5 is the first Tamagotchi to be exactly the same (besides language) in Japan and elsewhere, since the Tamagotchi Plus. It was released in Asia on 6 January 2008, Australia on the 10th January 2008 and elsewhere in February 2008.
A new feature is that you can raise Tamagotchi Families, with up to 3 kids, and on Generation 2 or higher, two parents. It, however, is not able to connect to the older Tamagotchi releases. It also has a new website that it shares with the Famitama, the Tama and Earth Expo. According to the package, Bandai quotes, "The Tamagotchis set up this expo to learn more about Earth." It contains a central pavilion, and 4 other pavilions representing each of the 4 main regions where Tamagotchi pets are sold.
It also included a TV option where the player can use Gotchi Points to shop on the Shopping Channel (equivalent to the Shop), find a mate with the Dating show (the equivalent of the Matchmaker), or go traveling on the Traveling Show, which is the V5 variation of the pause mode. Players can raise families like the Mame family, the Kuchipa family, and Neglected families like the Ninja family. The antenna is shaped like a rectanglar house or a chimmney, but like previous models, the antenna is for decoration. The Japanese equivalent has, instead, a hoop for a key.
The Tamagotchi Mini' (known as the Chibi Tamagotch in Japan) is a miniature Tamagotchi 66% of the size of the original toy which has limited features and is promoted as a fashion accessory.
In Japan, the three colors available were identical to three of the six colors of the original Tamagotchi (pink, light blue, and white). The keychain attachment is a small ball chain loop. In America, it debuted with four colors (black with flames, light blue, pink, and purple) and several months later followed with four more colors (yellow with dots, purple with dots, a darker blue, and yellow with stripes). The keychain attachment is a short link-chain with a lanyard clasp at the end. In Australia, it debuted with the Japanese colors, chain, and packaging; but had American programming.
There are 7 adult characters and a toddler (Marutchi), which are the same as the ones in the Generation 1 original Tamagotchi. There is also a secret character only available in the Japanese version (Unchi-kun). The English edition replaces him with Ginjirotchi. A special New Year's edition debuted in Japan in 2007, featuring two new secret characters and new foods.
Modern Releases Exclusive to Japan (2004–Present)
Keitai Kaitsuu Tamagotchi Plus
The Keitai Kaitsuu Tamagotchi Plus, known as the K-Plus is capable of connecting to Japanese mobile phones. In order to connect the Tamagotchi with cell phones, cell phone users first have to download a Tamagotchi game onto their phone. Afterwards, when connecting, the Tamagotchi could do many things, such as visit its parents, play games, and even find a mate. It connects to the original Tamagotchi Plus and the Deka Tamagotchi models. Ten digit passwords unlock food from each region of Japan and items for the Tamagotchi. The K-Plus features old characters as well as new characters not in the original Tamagotchi Plus.
Tamagotchi Plus Akai
The Akai was released July 23, 2005 in Japan. It is similar to the Keitai Tamagotchi but it features mono-color red LCD. There are new red-theme characters including a tomato, daruma, tengu, heart, and cherry, and new red-theme foods including pizza, wine, peaches, and red rice. The games are the same as the Keitai and Hanerutchi Tamagotchi with different graphics. It is capable of connecting with Japanese mobile phones, the Keitai Tamagotchi, Deka Tamagotchis at stores in Japan, the Home Deka, and the Hanerutchi Tamagotchi.
The Hanerutchi features characters from the Japanese show "Haneru No Tobira" ("You Knock On The Jumping Door") and a small amount of Tamagotchi characters. It debuted in two colors with identical designs (white with green or red stripe and black), and a limited-edition metallic white with blue stripe was later released. It is similar to Keitai Tamagotchi with different characters.
This Tamagotchi is like the first Hanerutchi but is fashioned after the EnTama.
Chou Jinsei Enjoi Tamagotchi Plus
The Cou Jinsei Enjoi Tamagotchi Plus, commonly referred to as the EnTama was released November 2005 in Japan. The design features a large antenna with a ball at the end, and a small strand of beads is attached rather than a key chain or mini-strap.
The Entama is the first Tamagotchi to remove two of the Tamagotchi's original primary functions: the discipline and the lights (the Entama turns the lights out on its own at night).
It is the first Tamagotchi with the ability to link to the computer. The user would be able to play with the Entama on the computer by going to E-Tamago. From there, the user can enter Tamagotchi Town and take part in many activities and play many games. The user can even shop and buy things for the Entama, which are received via 14-digit passwords.
The Entama included lifelike features, such as schooling and jobs (with job interviews). What jobs and what education the Tamagotchi receives are based on Skill Points (known as GUTS points), which can be raised by playing games, using items, and eating certain foods. The user can also cook by mixing certain ingredient items together. The foods created through cooking all raise certain skill areas.
There are a total of 58 characters featured on this Tamagotchi (42 Basic characters, three Secret Characters, two oldies, Oyajitchi and 10 Call Dating Service characters, also known as Hatenazoku characters). It includes three character groups: Intelligence, Style, and Kindness, also known as Mamezoku, Memezoku, and Kuchizoku, respectively.
Ura Jinsei Enjoy Tamagotchi Plus
The Ura Jinsei Enjoy Tamagotchi Plus, also known as the UraTama, is an Entama refresh released in June 2006. It features a mono-color blue LCD, unlike most Tamagotchi pets, and includes a star replacing the round decorative "antenna" and beads. Three special designs were released to commemorate the 10th anniversary of the Tamagotchi franchise.
The TamagoChu is a minor Tamagotchi released at the end of January 2007 in Japan. TamagoChu's come in matching pairs, and with four different designs. The TamagoChu was mainly released for older audiences.
Unlike other Tamagotchi pets, virtually no care is required for the TamagoChu. There is no food, sickness, game, or bathroom functions. The user selects a teen character on each egg, who follow a linear growth. The TamagoChu include a fourth button (on the right side of the male egg and on the left of the female). Pressing the buttons together, the two eggs can communicate and develop a relationship. As the relationship grows stronger, the characters exchange items and grow up, having offspring and becoming old before leaving back to Tamagotchi Planet on a UFO.
The Odenkun was released on March 31, 2007 only in Japan, and features a shop owner. It is based on a Japanese cartoon, called "The Adventures of Oden-kun" in which all the characters are common Oden ingredients. The Tamagotchi has now ended production.
Royal Dream Family Tamagotchi Plus
The Royal FamiTama, as it is nicknamed, is a refresh of the FamiTama and was released March 29, 2008. Like the FamiTama, the Royal FamiTama has the option of a DVD, that will have new games and new items featured on it; 4 new games and 30 characters; it can connect with original FamiTamas and international equivalents; and includes about 60 new items.
Tamagotchi Plus Color
The Tamagotchi Plus Color (commonly abbreviated as TMGC+C) was the first Tamagotchi to have a full-color back-lit LCD screen. It debuted as a Japan-exclusive release on November 22, 2008, though a special release was held the week before. Compared to earlier versions, the shell is larger and thicker, and features a covered screen, much like the TamagoChu. The classic "cracked egg" design no longer borders the screen, but instead borders the Bandai copyright notice on the battery cover on the back. The TMGC+C maintains an infrared port at the top of the shell. It uses two AAA size batteries instead of the usual button cell batteries. 11 shell patterns are available: White, Pink, Magenta, Black, Blue, Orange, Green, Yellow, Navy, Green+White, and Cream+Pink.
A new function allows the character to leave their home and visit all parts of Tamagotchi Town on the device, as opposed to visiting locations through an online interactive website. Users can play games, visit stores, take walks, etc. Characters also get "dirty" over time, showing them brown on-screen, and cared for by using an icon shown as a shower head.
Since its release in Japan, many Tamagotchi fans outside of Japan have put up protest sites featuring polls and surveys being sent to Bandai requesting them to distribute the TMGC+C in other countries.
EXmotchi was a special edition of the TMGC+C, promoting the Japanese band Exile. There were two shell patterns: Red, and White. Both feature the name "EXILE" written above the screen and "TMGC" written below the screen. Other than a different shell pattern, the EXmotchi was exactly the same as a regular TMGC+C.
The Hexagontchi is themed on the Japanese quiz show "Quiz Hexagon II". It is available in two shell patterns: Red+White, and White+Red. The Hexagontchi is similar to the regular TMGC+C except in order to extend the happiness bar, a series of quiz-show-style questions must be correctly answered. It also features some hexagon-themed items and room styles.
The Tamagotchi iD is the latest color Tamagotchi. It has many new features such as changeable accessories, keeping the same character, mobile accessibility, downloadable items from the Tama-iD.com web site, a new 'friend' stage, photo studio, garden with a mail box and more new features. It was released on Mametchi's birthday on November 23, 2009.
It includes many new character such as a popstar character , Lovelitchi, used in Western Cultures.
The Tamagotchi Nano is the successor to the older Chibi Tamagotchi or Tamagotchi Mini, it features a larger screen, and New Characters such as Spaceytchi and Lovelitchi/Lovelin, in addition, you can attach them to the back of your Tamagotchi iD.
Tamagotchi iD L
This Tamagotchi is similar to the original iD, but has more features including the ability to clean the Tamagotchi's house, visit and share a meal with the Tamagotchi's parents and grandparents. It can also connect to Japanese cell phones like the iD. Many new characters were added.
Tamagotchi iD L 15th Anniversary Version
An upcoming release is for the Tamagotchi iD L 15th Anniversary Version, a refresh of the Tamagotchi iD L, for the 15th anniversary of the Tamagotchi franchise. Some of the characters on the Tamagotchi iD L are replaced by other ones selected by a poll on the Japanese Tamagotchi official website.
English Language Virtual Pets (2005–Present)
Tamagotchi Connection Version 2
The Tamagotchi Connection Version 2 was released on June 21, 2005 in the U.S. It is roughly the English equivalent of the K-Plus, minus the cellphone connection features. The Tamagotchi Connection Version 2 features newer characters and ones taken from older releases, such as the Osutchi, Mesutchi, and the Original Tamagotchi.
"Gotchi Points", or GP, were introduced. GP are earned by playing the games and are used to buy items from a shop. The maximum amount of GP that it is possible to earn is 9999. Caretakers can connect (using IR capability) with other users; the user is able to choose whether to play a game or give a present. The option to connect to either the original Tamagotchi Connection or Version 2 Tamagotchi was introduced. Five "codes" are available on the V2 that unlock special items.
Tamagotchi Connection Version 3
The Tamagotchi Connection Version 3 (also Tamagotchi Connexion Version 3 in Europe) was released on February 18, 2006. Like the Version 2, it borrows some features from the latest version of the Japanese toy, but greatly simplifies them. This means that the V3 does not go to school, get a career, or receive a salary. It debuted with 7 new colors, adding many more designs later on.
The Version 3 unit has a little antenna on the top left side, similar to the Keitai Tamagotchi. The 'antenna' distinguishes it from the other versions. There are over 20 new characters, many from Osutchi, Mesutchi and the Keitai, thus bringing the total number of Tamagotchi Connection characters to 52. It is able to connect with Version 1 and 2, as well as other V3 Tamagotchi pets.
The Version 3 can also be used with Tamatown.com which generates codes which the user can input into the toy and receive souvenirs, which are items that the user can look at (but the Tamagotchi cannot play with). Passwords also give the shop items and food, which cost Gotchi Points. The Tamagotchi can eat the food that the user buys in Tamagotchi Town. Other than the code from the Nintendo DS Game, the passwords unlocked on the pet or on TamaTown.com will not work on any other Tamagotchi, thanks to the username system on both Tamatown and the Tamagotchi itself.
There are six new games, as well as new games that the Tamagotchi play with each other when connecting. The winner gets a certain amount of points depending on what stage the connecting Tamagotchis are in.
Some souvenirs disappear after each previous generation, which is not a glitch but a feature. Souvenirs 2 (Town Hall Key), 3 (Key #2), 7 (Clean up game medal), and Souvenirs 18 to 21 (Arcade items players can win for free) disappear when the new generation appears. These are free items users can turn back on if they saved the passwords that turned them on in the first place. Souvenirs that users pay for with Gotchi Points (The Trip souvenirs) or donate points for (Ring, Cape and Crown from the Tamagotchi King) do not disappear.
Seven codes are available on the Version 3 that unlock special items, similar to the five codes for the Version 2.
The Version 3 is infamous for having more glitches than any other Tamagotchi model to date.
Tamagotchi Connection Version 4 has new connection options. Not only can the player go to this icon to connect to another Tamagotchi but can also use it to have their Tamagotchi go to school or to work.
The player can also use passwords to "login" to their computer to have their Tamagotchi in TamaTown which has info on the second paragraph. When the player wants to connect to another Tamagotchi they either can press V4 or Others. If the player presses V4 three options would pop up: Game, Present, and Visit. If the player chooses Games, the two Tamagotchi will compete in a randomly selected game for Gotchi points. If the player chooses Present, their Tamagotchi give the other Tamagotchi a gift. If the player chooses Visit, one Tamagotchi will go to the other Tamagotchi and spend time together. On the other hand, if the player chooses Others, they will be able to connect to the older Connections and the two Tamagotchp://v4.tamatown.com/tamaok.html Tamagotchi Town]. The "antenna" on this version is a star or, in Europe, a ball (like version 4).
It retains the feature of skill points, but has new types of them: Funny, Gorgeous and Spiritual. It has five games to play, like the V4: Climb, Tug-Of-War, Apple, Shapes (entirely different from the "Shape" from the V4) and Manhole. The baby takes one hour to change into a toddler. From then, it takes one day to change into a teenager. Then it takes two days to change into an adult.  Like the features from Versions 2-4, V4.5 has secret codes that the player can enter into the Shop Keeper. The release date for the US was June 25, 2007.
Tamagotchi Connection Version 5.5 Celebrity
The Tamagotchi Connection Version 5 Celebrity is a Version 5 refresh exclusive to North America, Australia and New Zealand. While it is known as the V5 Celebrity in America, it is known as the V5.5 in Australia and New Zealand. It is based on the Royal Dream Family Tamagotchi Plus, with an addition of several exclusive items, characters, and 2 bonus games.
Tamagotchi Connection Version 6 Music Star
Tamagotchi Music Star (billed as the Tamagotchi Connection Version 6 or V6 in the Asia/Oceania/Australia region) is a Tamagotchi released in North America on November 28, in Europe in January 2009, and in Asia/Oceania/Australia in February 2009. The Music Star features a 48×31 screen, similar to the one introduced on the Tamagotchi Connection Version 5, but the shell does not feature an antenna, much like the Tamagotchi Connection and Tamagotchi Connection Version 2. 12 designs are available in the USA, and 18 in the Asia/Oceania/Australia. The Tamagotchi starts off with an instrument, toy, and some money. At the child stage, the Tamagotchi goes to preschool and receives a new toy. At the teen stage, they go to the Gotchi Performing Arts School (GPAS) and join a band with two other characters. The new band is taught by Classictchi until the band members reach adulthood.
As adults, they perform in front of a panel of judges. If any judge votes "no", the band can only do street performances until their next attempt. If the judges all vote "yes", the band debuts as a professional band.
TamaTown by Tamagotchi
This product line was first released in Fall 2010, featuring a larger Tamagotchi unit, or the Tama-Go, along with Gotchi Figures to plug into the Tama-Go. The TamaTown website, formerly known as "Music City", is now used for both the Tamagotchi Music Star and the Tama-Go.
The TamaTown Tama-Go (retailing for approximately $20) features a new four-color grayscale LCD screen, unlike the full-color screen of the Tamagotchi +Color or iD. Instead of using CR2032 batteries, like previous internationally-released Tamagotchi devices, the Tama-Go utilizes 2 AAA batteries. The Tama-Go attempts to mimic the functions of the +Color, offering features like customization of one's house. Along with many of the basic Tamagotchi features, the Tama-Go also allows users to visit a great, amazing TamaTown in the device itself. With this feature, users can navigate their Tamagotchi to a park, where it can play with a computer-controlled Tamagotchi, a carpenter, for customizing one's home, and a dating center, used to find a mate for one's Tamagotchi.
TamaTown Character Figures are electronic cartridges designed for the TamaTown Tama-Go. One kind, "lite figures", contain just one game, and are included with the Tama-Go. Full Character Figures (retailing for approximately $7)can also be purchased. These figures contain two games and a shop for the Tama-Go unit.
Bandai America sells a TamaTown Carrying Case (retailing for approximately $15), which contains contains enough space for one Tama-Go and twelve Gotchi Figures.
Arukotch is not exactly a virtual pet, unlike most Tamagotchi releases. It is a combination of a pedometer and a game. When the user walks while wearing it, a character in the Arukotch called Arukotchi walks on the screen, and she may meet a boy Tamagotchi. Arukotchi may also find an item which makes her more attractive to the other Tamagotchi while she walks.
Mezamatch is a combination clock and virtual pet. It resembles a large Tamagotchi. You can also save dates, such as anniversaries and birthdays, on the device.
Mechagotch is a calculator. There are two modes which one can use it in, in addition to three games. One mode is a normal calculator, and one is a calculator with a Tamagotchi who reacts in different ways depending on the calculation. When one first uses this mode, there is an egg on the screen. It hatches into a different character depending on the last two or three digits in the answer to the first calculation which the user does in this mode. After the character hatches, the character reacts in different ways depending on the answer to the subsequent calculations. The numbers also show up in different ways depending on the character (for example, the answer might show up right away, or they might "spin" through several numbers in a similar way to a slot machine, depending on the character).
There are also three games. The first game is a kind of blackjack game, the second game is a game in which the player has to guess whether the number is higher or lower than the one displayed on the screen, and the third game is a memory game.
These Tamagotchi were put in stores around Japan. The owner of a Tamagotchi could connect their Tamagotchi to get a special character on their friends list, and Keitais, Akais, TamaSukus, and Entamas could connect to buy items from the Deka. There are 4 main versions, Lotteria, Tamatama market, Game Station and Jukutama. There were not put for sale, but it is possible to buy them online.
Ouchi no Deka Tamagotchi (Home Huge Tamagotchi)
Home Huge Tamagotchi (おうちのでかたまごっち o-uchi no deka tamagotchi ) is a version of the "Huge Tamagotchi" which could be bought by individuals for home use. It was released July 2005 in Japan. It includes a stand for tabletop display, three-position volume adjust, and requires 2 AAA batteries.
The player is a female Tamagotchi character that initially lives in a small house in TamaTown. Through playing games and banking Gotchi Points, one can upgrade their house several times, the end result being a large Japanese-style palace. Each time an upgrade is performed, the capacity to keep various pets is increased. It is also possible to purchase a wide range of items to decorate the inside of the house, or to transfer over to the portable tamagotchi toys.
A special green-colored edition was sold at Japanese Toys-R-Us stores, available either paired with a matching Akai series toy or alone.
The Tamagotchi Kakeibo (超やりくりエンジョイ！たまごっちかけいぼ chō yarikuri enjoi! tamagotchi kakeibo) is an accessory for the Entama-generation Tamagotchi toys released in Japan.
It is slightly smaller than a home dekatama and very thin, as it is designed to fit into a small binder included with the toy. Inside the binder is a starter pack of "account book" (kakeibo) pages used to track the user's spending of "gotchi points", the currency used in all Tamagotchi toys. Initially released with a pink body and orange stylus, a later version released around the same time as the uratama features a blue body and green stylus, new screen background, and new binder cover (although with the same black-pixel LCD and programming).
The kakeibo is not really a virtual pet like the other portable tamagotchi, but more of a tool to assist with caring for them. Users play as Osewatchi (likely from the word o-sewa; help or aid), a female Tamagotchi who lives in Tamagotchi Town's Ginza district, which is the Tamagotchi Planet's version of the fashionable Tokyo shopping district. There are many stores which sell items users can transfer to their Tamagotchi pets, a bank to store money, as well as mini-games to earn that money and a library which can record which Tamagotchi characters players have discovered on their Entama and Uratama.
Tamagotchi "Music Fever"
The Tamagotchi "Music Fever" is a Tamagotchi that can record music off of CDs or cassette tapes. It is somewhat similar to the iPod. There are also a few games that can be played on the MusicFever device. 
Tamagotchi School (たまごっちスクール tamagotchi sukuuru ), also known as TamaSuku (たまスク), was released in Japan on November 23, 2006. It is the second Tamagotchi that is horizontal, first being Arukotch. It also is the first Tamagotchi to use a directional pad, and the second Tamagotchi to have only "select" and "cancel" buttons, the first being the Yasashii Tamagotchi.
