Blocks labelled with kanji fall toward the bottom of the screen. The point of the game is to shoot down the blocks with missiles labelled with pronunciations.

If a missile with an incorrect pronunciation hits a block, the block is not destroyed. If the block reaches the bottom of the screen, it explodes and causes the player damage. When the player’s life bar is empty, the game ends.

In the gameplay menu, the player can control how many blocks there are and how fast they fall.
