Tetris MicroCard is a credit card sized handheld Tetris game based on the Arduboy. Unlike the Arduboy, neither the hardware or software is open source.
There is one game mode, a basic endless Marathon style game. The player can start on any level from 1 to 15.
Scores over 10 million are saved and ordered on the local leaderboard correctly, but do not display the most significant digit.
