64 de Hakken!! Tamagotchi: Minna de Tamagotchi World

64 de Hakken!! Tamagotchi: Minna de Tamagotchi World is a party board game based on Bandai's Tamagotchi toy line. After a UFO with Tamagotchis crashes into Doctor Banzo's head, he is inspired to build a house which can raise up to four Tamagotchi. The player must compete against three opponents and travel around a board to be the fastest one to fully raise their Tamagotchi. Up to four players can compete against each other, with a computer opponent replacing any missing players. The game can be played with each player using a different controller, or with all players sharing the same controller.

During gameplay, the screen is divided into two separate parts. The top part of the screen shows the Tamagotchis in Doctor Banzo's house, while the bottom part of the screen shows the board and the players. Each player moves by rolling a dice block, with the amount of spaces that they move being dictated by the number on the die. The player's goal is to collect enough transformation power points to evolve their Tamagotchi a certain amount of times. The Tamagotchi's progress towards evolution is represented by the bottom guage on the top screen. The player can earn transformation power points through various methods, such as landing on certain spaces marked with a plus sign or by completing minigames. If each player is using a separate controller, there are ten minigames to play, while if all players share the same controller five minigames can be played. There are various other spaces which can be landed on, such as spaces which grant cards that the player can use or accident spaces, which can either give or take away transformation power points.

In addition to the transformation power points, the player must also consider their Tamagotchi's mood and hunger gauges. These gauges are presented on the top screen, and the higher they are, the more transformation power points the player can obtain. After each player's turn, they can perform an activity with their Tamagotchi, such as feeding them or playing a game with them. This helps to keep the gauges higher, and it is important for them not to reach zero as the Tamagotchi will otherwise die and the player will be unable to continue. The player's Tamagotchis can also die from sickness, so the player must be sure to remove their waste so their Tamagotchi doesn't fall ill. Once one player's Tamagotchi reaches the highest level the game is over and the player can save an egg produced by their Tamagotchi, which they can save and use in their future matches.
