The game
What is Block Blast?
Block Blast is a relaxing block-puzzle game. You are given three block shapes at a time and drop them onto an 8×8 grid. Fill a complete row or column and it clears, freeing up space and scoring points. There is no timer and no move limit — the only way to lose is to run out of room for all three of your blocks.
It sounds simple, and the first few hundred points are. Pushing past a few thousand takes real board management: keeping space open, reading all three pieces before you place any, and lining up two or more clears at once for combo bonuses.
Play in the browser

How to play Block Blast
Drag a block onto the grid
Pick any of the three shapes in your tray and drop it on an empty area of the 8×8 board.
Fill a row or column
Complete a full line of 8 cells — horizontal or vertical — and it clears, giving you points and space.
Chain combos
Clear lines on consecutive placements, or clear multiple lines with one block, to multiply your score.
Keep room for all three
The game ends only when none of your three blocks can fit. Manage space and it never has to end.
