Tetris Blast is the North American version of Bombliss. It features many unique Tetris modes mainly dealing with clearing the screen of all blocks by using bombs which were both given at the start as well as in the tetrominoes. In addition to the tetrominoes of other Tetris games, Tetris Blast also uses dominoes and triminoes.

Game play

Each falling piece contains at least one bomb. Most contain one bomb, not in a position horizontally or vertically between other blocks (for example not in the center of an L, J, or T), but every eighth piece is made entirely of bombs. When rows of the playfield are filled, they do not disappear as in other games; the bombs within the row explode depending on how many rows are filled at one time. It is possible for rows to be filled with no bombs, which increases the size of the next explosion.

Four bombs arranged into an O shape will become a larger bomb. Unlike in The New Tetris, the game checks for this after all explosions, meaning that large bombs can be formed only in rows that still have a gap. Unlike in Lumines, large bombs cannot be made of overlapping blocks.

Tetris Blast uses the sticky style of line clear gravity, allowing pieces unconnected to anything to fall. This allows chain reactions.

Explosion size table

Explosions happen when a row is filled containing a bomb, or when another explosion reaches the bomb. Each explosion is in the shape of a rectangle centered about the center of the bomb.
