Block Blast Master is a block puzzle game that requires the player to create eight-block lines on an 8x8 dark blue grid using colorful polyomino shapes. The player attempts to earn a score like no other without running out of space. If they do run out, the game doesn't offer a revive option. The player must then attempt to beat their last high score, which the game displays near a gold crown in the upper-left corner.
The player drags each polyomino shape to the grid to create the column and row lines. They receive more points if they create lines in a streak (i.e., one after the other without disruption) or they form partial lines and then use one shape during one move to complete all the lines. In the second scenario, for example, they might partially complete four lines with one block missing at the same end of each one and then drag a vertical four-block polyomino shape to that position.�
When the player completes combination moves as outlined, Block Blast Master adds a pulsating pink heart to the current score zone in the top-center position behind the white numbers. If they continue their streak, the heart remains on the screen. Once they stop, it disappears.
