How to Use Block Blast Solver?
Block Blast Solver is a free tool that helps you find the best placement order for your current pieces.
Set up the board: Click cells on the 8×8 grid to mark which squares are already filled (purple = occupied block).
Draw your 3 pieces: Click cells in each 5×5 Figure grid to draw the exact shape of each piece shown in your game.
Solve and play: Hit Solve — the tool finds the optimal placement order and shows you the result board after each step.
How does Block Blast scoring work?
Completing a full row or column clears it immediately and earns points. Clearing multiple lines in a single placement multiplies your score. The solver prioritizes moves that clear lines while keeping the board open for future pieces.
Top Block Blast tips
Plan all 3 pieces first: Never place without knowing where the other two go.
Keep the center open: Large pieces need flexible space — don't clog the middle.
Chase near-complete lines: Rows/columns missing 1–2 cells are your top priority.
Avoid isolated gaps: A cell surrounded on all sides can never be filled.
