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. Not only the usual tetromino standard to Tetris games, Tetris Blast also uses dominoes and triminoes.
Game play
Each falling piece contains one bomb. 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.
