It is the smallest game system with interchangeable cartridges ever produced by Nintendo,[5] weighing just under two and a half ounces (71 grams).

[8] The system was released in three colors: Wooper Blue, Chikorita Green, and Smoochum Purple.

[2] Features of the Pokémon mini include an internal real-time clock, an infrared port used to facilitate multiplayer gaming, a reed switch for detecting shakes, and a motor used to implement force feedback.

It includes six minigames which all take advantage of the system's capabilities and abilities: Additional modes include "Battlefield", where two to six players battle for the highest score in the aforementioned minigames, and "Celebi's Clock", a clock with date, alarm and stopwatch function.

It features six new minigames based on the Pichu Bros. specials: The "Battlefield" and "Clock" modes also return from the original.

Togepi's Great Adventure[j] is a top-down action puzzle game developed by Jupiter.

The player guides Togepi out of maze-like levels in a tower while avoiding obstacles and other Pokémon.

One of these games, "Snorlax's Lunch Time", was never part of any commercial Pokémon Mini release.

This allowed them to build new emulators to run the games on other devices, such as the PC, Dreamcast, Nintendo 3DS, and Analogue Pocket, among others.

[16] These efforts also led multiple programmers to create homebrew applications for the system, such as original games and tech demos.
