About This Tool
Block Blast is an 8×8 grid puzzle. Drag pieces from the tray onto the board. Complete a full row or column to clear it and score points. Chain consecutive clears for combo bonuses. When all 3 tray pieces are placed, 3 new random pieces appear. The game ends when no remaining piece can fit anywhere on the board.
How to Use
Drag a piece from the tray at the bottom onto the 8×8 grid.
Green preview means the placement is valid; red means it does not fit.
Complete a full row or column to clear it and earn bonus points.
Chain consecutive clears to build a combo multiplier for a higher score.
When all 3 tray pieces are used, a fresh set of 3 appears automatically.
Game over when none of the current tray pieces fits anywhere on the board.
Frequently Asked Questions
How do I clear a line?
Fill every cell across an entire row or down an entire column. If a single piece completes both a row and a column simultaneously, both clear at once.
What is a combo?
Each time you place a piece that clears at least one line, the combo counter increases. A combo of 2× or higher multiplies the line-clear bonus.
When do new pieces appear?
After all three tray pieces have been placed, a new set of three random pieces appears.
