テトラコンボ (Tetra Combo) (2014)

In テトラコンボ (Tetra Combo), each player controls four colored blocks on a 4x4 game board. They alternate taking turns, moving one block on each turn in order to create tetrominos, a tetromino being a pattern created by four adjacent blocks. (Think of the pieces in Tetris, with five tetrominos being the only shapes possible.) Each time that a player creates a tetromino — whether with their own pieces or with four empty spaces on the game board — that player scores a point for that particular type of tetromino. If you manage to create two more of a tetromino than the opponent, you win!
