The Tamagotchi Connection (UK: Tamagotchi Connexion) is a virtual pet in the Tamagotchi line of digital toys from Bandai. The Tamagotchi Connection is unique from prior models in that it uses infrared technology to connect and interact with other devices and was first released in 2004, 8 years after the first Tamagotchi toy. Using the device's infrared port, the virtual pet (referred to as a Tamagotchi) can make friends with other Tamagotchis, in addition to playing games, giving and receiving presents and having a baby. Versions 1 to 4 of Tamagotchi Connection have 6 levels of friendship that can be viewed in the Friends List: Acquaintance (one smiley-face) Buddy (two smiley-faces) Friend (three smiley-faces) Good friend (four smiley-faces) Best friend (two love-hearts, two smiley-faces, during connection they may kiss) Partner (four love-hearts, during connection they will kiss and may have babies) Versions 5 and 6 have different levels. If the Tamagotchi cannot find a partner from another device to have babies with, a matchmaker will come, allowing the Tamagotchi to have a baby with a computer-controlled Tamagotchi character. This applies to versions 1 to 4 and 6 only. Version 5 introduces a Dating Show game in which the user must play to gain a CPU partner. Versions All Tamagotchi Devices are capable of connecting with each other; however, a character from a newer Version will show on an older version as the mystery character known as Nazotchi. Tamagotchi Connection v2 (2004) The Tamagotchi Connection v2 introduces "Gotchi Points", an in-game currency used to buy shop items. Also, more games are unlocked as the Tamagotchi ages. It has 6 stages of life: Egg - This only occurs once the device has been reset, either by pressing the reset button on the rear of the device or by installing a new battery. Once the clock has been set, it will hatch in one minute. Baby - The baby unlocks the game Jump. Child - The child unlocks the game Bump. Teenager - The teenager unlocks the games Flag and Heading. Adult - The adult unlocks the game Slot. Senior. The senior can only be unlocked if the Tamagotchi stays unmarried for a certain amount of days. This applies to all versions. Tamagotchi Connection v3 (2006) Aside from different games, The Tamagotchi Connection v3 makes few changes in comparison to the v2. Like the v2, the older the Tamagotchi gets, the more games
