Building a free puzzle solver – from frustration to launch

I built Online Block Blast Solver because I kept getting stuck in Block Blast with no idea where to place the next block.

The game starts easy. Then suddenly the grid fills up, and you're staring at three blocks with no valid move. I'd try every possible placement, lose, and restart. The worst part was not knowing if I missed a good move or if the board was genuinely unwinnable.

So I built a tool that analyzes the board and suggests the optimal move sequence. It simulates all possible placements, scores each outcome, and shows you the best path forward.

The tool is free. No ads, no sign-ups, no tracking. Runs entirely in your browser.

I'm sharing this here because I know other players face the same frustration. And I want to hear from other builders — how do you approach puzzle logic? What would you improve?
