That one-player game consists in facing nine opponents through duels with individual screens. Each one in his playground have to stack blocks composed of three different colored helmets. Like Tetris, it is possible to rotate, move left or right or accelerate the fall of these blocks. Starting from three identical helmets lined up horizontally, vertically or diagonally, they explode and generate a bomb in the playground. When they disappear, they can initiate chain reactions, for example with the blocks lying above falling. After a certain number of removed blocks, comes an activated bomb: player have to place it in order to make the most of these bombs explode on his table.
