Is this Block Blast solver free?

Yes — it is free to use. No downloads or account are required.

How does the solver work?

It tries every valid placement for your pieces, simulates row and column clears after each move, and ranks results by total score. Typical solve time is under 200 ms.

Does this work as a blockblast solver or Block Blaster solver?

Yes. Many players type blockblast solver without the space. The tool also works for Block Blaster and similar Block Blast-style games with fixed pieces, no rotation, and row or column clears.

Can I solve Block Blast from a screenshot?

Yes. Upload a screenshot, align the draggable detection frame with the board, then click Apply to board. The image is processed locally in your browser and is not stored.

Will the solver remember my screenshot detection frame?

Yes. After you align the frame, use the Cell detection slider if the filled cells detected count looks wrong, then click Apply to board. The frame size and position are saved on the same device for that board size.

What is the difference between Max Lines and Est. Max Score?

Max Lines prioritizes clearing the most rows or columns. Est. Max Score ranks moves by an estimated score model based on cleared cells, multi-line clears, and combo streaks.

Can I solve with fewer than 3 pieces?

Yes. You can solve with one, two, or all three visible pieces. Using all three usually gives the most complete recommendation.

Is this an official Block Blast tool?

No. This is an independent tool for Block Blast and Block Blaster-style puzzle games, not affiliated with or endorsed by the official game or its developers.
