Tamagotchi Nano (たまごっちナノ or たまごっちnano), stylized Tamagotchi nano, is a series of miniature virtual pets that were first introduced in 2010 and were reintroduced in 2017 as a medium for crossover-themed virtual pets.

Initially, the name "Tamagotchi Nano" was only used for the first two virtual pets in the series, and all releases are referred to internally as "Tamagotchi Nano" models. In August 2021, Bandai Japan reintroduced the name as its own distinct brand of Tamagotchi pets. As of June 2022, Tamagotchi Nano has a total of 28 different versions, more than any other Tamagotchi franchise.

Design

Nano diagram.png

The Tamagotchi Nano is a miniature virtual pet that measures at about 4 centimeters tall, or about 1.57 inches. It has a rounder, more egg-like shape, making it thicker than a normal Tamagotchi and slightly bigger than the Tamagotchi Mini. The front of the shell has a droplet-shaped frame around the screen with three buttons below, and the screen itself is deeply recessed into the body of the shell.

The battery panel has a rectangle with "cracked" patterns on the left and right side. At the bottom of the battery panel is either a pressure-sensitive tab or a screw, depending on the model. Like the classic Tamagotchi, Nanos take two LR44 batteries. The speaker is at the top of the back, and the two screws needed to open the unit are covered by plastic tabs, which must be broken off to access them. The "Reset" button is on the top right, below the right screw and above the battery panel.

In addition to the standard mold, the first wave of original Tamagotchi Nano models featured a mold with a crystal-like outer frame, which has not been used since. The Pac-Man Tamagotchi and the Hello Kitty Tamagotchi both use a unique mold different from Japanese models. The droplet frame and shell front are a single mold, making the gap between them thinner and allowing graphics to be printed over it. The two screws on the back are uncovered.

The classic Nano models and the Pocket Usatama 2017 feature a 24x24 pixel screen. From the Gudetama Tamagotchi onward, all Nano models have smaller pixels but a wider screen of 30x24 pixels.

The initial two versions of the Tamagotchi Nano are distinguished by the background print; the first version's background has a floral pattern at the upper right and bottom left corners of the screen, and the second version's has a wave pattern across the top and bottom halves of the screen. There are three shells exclusive to the Tamagotchi Department Store which have the store's logo as the background. None of the licensed versions released afterward have had background prints.

There are three different types of ball chain. The standard ball chain is identical to the one first introduced with the TamagoChu, with round and oblong beads. A second type of ball chain, with round, small beads, is used on the Pac-Man Tamagotchi and Hello Kitty Tamagotchi. A third type, featuring round, larger beads, is used on many of the later models.

Most models were made in China, while several later models were made in Vietnam.

Menus on the screen are typically portrayed with Japanese or English text. Later models have used graphics for the menu options instead, allowing models to be distributed globally without the need of translating the device's text.

Accessories

Cases

A Pocket Usatama case.

A common accessory for early Nano models are cases. As all Nano models are the same size and shape, any case can hold any Nano model, with the exception of the two crystal Tamagotchi Nano shells that may not fit in some thicker rubber cases. Cases have been produced themed after both versions of the Pocket Usatama, the Gudetama Tamagotchi, the Pocket Usapiyo, the Pac-Man Tamagotchi, and the Jordy x Tamagotchi.

All Nano cases feature a droplet-shaped hole to insert the Nano inside, which leaves the frame, screen, and buttons of the Nano exposed while the rest of the shell is protected. This allows the Nano to be used without removing it from the case. Cases will always have a hole on top to insert the ball chain, and most cases have a round hole for the Nano's speaker. Some cases, including the sitting Gudetama case and the Pac-Man case, have a flattened bottom, allowing it to stand upright on a flat, level surface.

Hugmy Tamagotchi

A Hugmy Tamagotchi is a desk accessory used to hold a Nano upright on a desk. They are approximately 4 inch tall collectible character figures made of soft vinyl and have articulated arms and heads. Their arms and legs are set to position where they can hold a Nano securely, with the legs having indents. While the figures can hold a Nano security with or without the chain, removing the chain is recommended. As with cases, any Hugmy Tamagotchi figure can hold any Nano model.

Hugmy Tamagotchi figures are always sold bundled with a respective Nano as a "Hugmy Tamagotchi Set". Four figures were produced for the Jujutsutchi, each bundled with a shell matching the character. The TinyTAN Tamagotchi introduced an additional seven, each bundled with an exclusive black shell not sold individually.

Other Accessories

A Kamen Ridertchi lanyard.

Several Nano models were accompanied with special accessories, either bundled with the unit or sold separately. The Pocket Usapiyo's cases were each bundled with lanyards. Preorders of the Evatchi at the official Evangelion store in Japan came bundled with charms featuring the sprites of Sachiel, Zeruel, and Gaghiel. The Twistetchi comes bundled with charms matching the dormitory the shell is based on. Lanyards were also made for the Jujutsutchi and Kamen Ridertchi, but were not available at retail; the Jujutsutchi lanyard was exclusive to Jump Festa 2022, while the Kamen Ridertchi lanyard was sold exclusively at the Kamen Rider Store.

Common Functions

Growth

The baby of the pet is born after the clock is set. On the original Tamagotchi Nano models, the Pac-Man Tamagotchi, and the Hello Kitty Tamagotchi, an egg appears and hatches after one minute. On all other licensed models, an introductory animation plays instead.

Once the pet is born, its growth is determined by the quality of the user's care, their game performance, and other influences depending on the model. On most models, it takes 24 hours before it evolves into its next form. On some models, there may be secret forms it can evolve into once certain conditions are met.

Buttons

Tamagotchi Nano models have no on-screen icons, and therefore all information is conveyed through the screen and buttons. The pet is cared for by filling its meters; they have Hungry and Happy meters, each consisting of four units, which are both empty when they're born. On all models, the Hungry meter decreases by one unit per hour, and the Happy meter decreases by one every 50 minutes. If either becomes empty, the pet will call for attention to fill them.

The user can press the C button for an animation to see what it needs. A dizzy spiral signifies an empty Hungry meter, while a sulking lines signify an empty Happy meter. Once the meters are not empty, the animation will change, typically to a Close Up. On some models, there are different animations depending on whether the Happy meter is partially or completely full.

Pressing the A button opens the main menu, with the first option for the food menu, and the second option for the games. The meal option fills one Hungry unit, and the pet will refuse to eat anymore once the meter is full. The snack fills one Happy unit, and can be fed even when the Happy meter is full. The A button is also used to open the lights on and off menu when the pet has fallen asleep. Babies sleep at 8 PM, while adults sleep at 10 PM. All pets wake at 7 AM, and will turn the lights on themselves when they wake up.

Pressing A and C together will open the menu or turn on or off the sound. Pressing the B button will open the clock screen, and pressing A and C together will allow the user to set the time. These two functions are always available regardless of the character's circumstances, except when it has died or departed.

Games

The initial Nano models, the Pocket Usatama 2017, and the Gudetama Tamagotchi all feature one game each. From the Eevee x Tamagotchi onward, all models have at least two games, with the exception of the Extellatchi. Games increase the pet's Happy level; winning the game fills Happy by one unit, while a perfect game fills Happy by two. On most models, which games are played in the pet's life may determine its evolutions.

Several minigame templates have been reused between models:

  • Catch/Dodge: The user controls a platform at the bottom of the screen, moving it left with the A button or right with the B button. Depending on the game, the user must catch a falling object, avoid an incoming object, or both.
    • This game template was introduced on the original Tamagotchi Nano, and appears on the Eevee x Tamagotchi, the Pocket Usatama 2019, Pocket Usapiyo, the Evatchi, the R2-D2 Tamagotchi, the Jujutsutchi, and the Demon Slayer Tamagotchi Yukaku Edition.
  • Dance: An animation plays, and then the user is prompted to press either the A or B button, once or twice. The game goes for five rounds. The user must successfully respond at least once to win the game, and five times for a perfect game.
    • This game template was introduced on the Eevee x Tamagotchi, and appears on the Pocket Usatama 2019, Pocket Usapiyo, all three versions of the Demon Slayer Tamagotchi, the Jordy x Tamagotchi, the Extellatchi, the Twistetchi, the BT21 Tamagotchi, the R2-D2 Tamagotchi, and the Jujutsutchi.
  • Slots: Three spinning slots appear with three possible images. Pressing A or B stops the slots one at a time (left first, then middle, then right). The game last five rounds, and after the third round, the slots will spin faster. The user must successfully match the images five times for a perfect game.
    • This game template appears on the Pocket Usatama 2019, Pocket Usapiyo, the Jordy x Tamagotchi, and the R2-D2 Tamagotchi.
  • Dash: The user must rapidly press the A button for a set time, typically 15 seconds. If the user presses the A button 9 times or less, the game is lost. Pressing the button 10-14 times is considered a win, and 15 times or more is considered a perfect game.
    • This game template was introduced on the Pocket Usapiyo, and appears on the first two versions of the Demon Slayer Tamagotchi, the Jordy x Tamagotchi, the BT21 Tamagotchi, the R2-D2 Tamagotchi, and the Kamen Ridertchi.
  • Targeting: The user must press A or B at the right time, when an image lines up in the correct way. The game has five total animation frames; the frame to press the button will be the third, fourth, or fifth frame of the animation. The user must respond successfully at least once to win, and five times for a perfect game.
    • This game template was introduced on the Evatchi, and appears on all three versions of the Demon Slayer Tamagotchi, the Jordy x Tamagotchi, the BT21 Tamagotchi, the PUI PUI Molcartchi, and the Toy Story Tamagotchi.
  • Drive: The user must press the A or B button to move their character up and down to avoid obstacles appearing on the left side of the screen.
    • This game template was introduced on the Jordy x Tamagotchi, and appears on the PUI PUI Molcartchi, the Kamen Ridertchi, and the Toy Story Tamagotchi.

Obstacles

Obstacles are events that happen that prevent the user for caring for the pet. These may include the pet making a Poo, a dirty room, attempting to run away, being attacked, among many other possibilities. The user will not be able to feed or play with the pet until the obstacle is cleared by pressing the A button. If the user doesn't respond for a long period of time, the obstacle will have a larger impact on the screen, such as poo accumulating or the room becoming dirtier.

Negative Conditions

Severely neglecting the pet, or allowing an obstacle to stay around for too long (for example, failing to clean poo for a long time), will cause an ailment to happen to the pet. This typically includes Sickness or sulking. The A button must be pressed twice to alleviate this condition. Like with obstacles, the user cannot feed or play with the pet until the condition is cared for.

Daily Animations

On early models, the pet would perform a Close-Up animation each day at 10 AM, 2 PM, and 6 PM.

On later models, special animations play at specified hours throughout the day, each inspired by the franchise the model is based on. These animations will stay on screen for three minutes before disappearing on their own. Pressing any button will end the animation, but in some cases may trigger an additional animation to play.

Ending Sequences

After a prolonged time, the pet will leave its owner. Each model has its own unique departure sequences, including Death, but many have more than one sequence. Typically, there is a "good" ending sequence, and a "bad" one. Regardless of which ending occurred, pressing the A and C buttons together will trigger the life cycle to start again from the beginning.
