The Umi de Hakken! Tamagotchi (Tamagotchi Ocean in America), often referred to as the Umi no Tamagotchi, 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 Tamagotchi. 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 Tamagotchi, 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 Debiru no Tamagotchi, often referred to as the Devilgotchi, was released in Japan in May 1998 in four different colors for 2079. Some aspects of the care are similar to the Angelgotchi. However, while the Angelgotchi characters are eager to do good deeds for the caretaker, the Devilgotchi characters are mischievous and play pranks on the caretaker.
The Yasashii Tamagotchi 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. 
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.
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 seven new colors, adding many more designs later on.
The TamaTown Tama-Go includes a four-shade grayscale LCD screen, unlike the full-color screen of the Tamagotchi +Color or iD. Instead of using CR2032 batteries, like previous Tamagotchi devices, the Tama-Go is powered by 2 AAA batteries. The Tama-Go attempts to mimic the functions of the +Color, offering features like customization of one's house. This release has greatly increased in size, taking on an egg-shaped form-factor as opposed to the thin and portable Tamagotchi of previous releases.
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. This is the first Tamagotchi toy with a full-color screen to be released in both Japanese and English, though the English version is only sold in China and additionally was sold at Harrods in the United Kingdom.
In 2015, an upgrade was released, known as \"Tamagotchi Friends: Dream Town Digital Friend.\" It retains most features of Tamagotchi Friends while adding new features, but it can only be bought at online stores, primarily due to the lack of retailer interest in the product.
The Tamagotchi On was released in North America on July 28, 2019. It is the English equivalent to the \"Tamagotchi Meets\" released in Japan on November 23, 2018. It is the first widespread Tamagotchi release in the west to feature a color screen, along with the ability to connect to a mobile device using an app. It was discontinued due to the app closing down in 2022.
The Hanerutchi features characters from the Japanese show Haneru No Tobira (\"You Knock On The Jumping Door\") and a small number 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.
The Tamagotchi Plus Color (commonly abbreviated as TMGC+C) was a major turning point in the history of Tamagotchi, as it was the first ever 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.
The successor to the Tamagotchi P's, the Tamagotchi 4U (4U stands for Utility. Unique. United. Universal.) is the new model of the Tamagotchi released on September 27, 2014, with four colors, Pink, Blue, White and Purple. Unlike the other versions, the 4U removes the infrared sensor and implements the Near-Field Connection first seen in both the iD L and Friends. The near field connection is only used when the 4U syncs with a designated \"touch spots\", located all over Japan in order to download special items and content to the 4U.
Bandai has released several different m!x versions. The first two versions are the Spacy m!x and Melody m!x. The pattern on the front of the device varies between the two versions. Spacy m!x version has a zigzag stripe pattern while Melody m!x version has one with spots. Both versions come in three colors: pink, purple, and blue. A third version, the 20th Anniversary m!x, was released to celebrate the 20th anniversary of the Tamagotchi franchise. The anniversary m!x features a falling star design and comes in two colors, Royal Pink and Royal White. In 2017 a fourth version, Tamagotchi m!x Sanrio Characters, was released in collaboration with Sanrio, featuring characters like Hello Kitty. Two versions of the Sanrio Tamagotchi were released.A yellow version, and a pink limited version by Toys R Us Japan that came in a special gift package and was only available during the holiday season of 2017.
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.
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 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.
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.
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 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, the same day as the franchise's 10th anniversary. 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. It can connect to other Tamagotchi Schools for playing games, the Entama and Uratama to gain new students and exchanging \"Gotchi Points\", Tamagotchi Station, Tamagotchi Station 2, the \"jukutama\" (a Deka Tamagotchi for Tamasuku) and an interactive website where players can compete against other players.  59ce067264
