How to use the Block Blast Solver
- Copy your board. Tap each square that has a block in your game. Drag across squares to fill several at once, and tap again to empty one.
- Add your pieces. Choose up to three pieces exactly as they appear in the game. If a shape isn't in the list, pick Draw your own and sketch it.
- Press Solve. The solver checks every order and every position for your pieces.
- Follow the moves. Step through the plan with Previous and Next. Each step shows where the piece goes and which rows or columns clear.

What the results mean
- All pieces fit: the solver checked every possibility and found the best sequence by its ranking. It prefers placing all of your pieces first, then clearing the most lines, then leaving the most open board, with room for big pieces and no boxed-in single squares.
- These pieces can't all fit: every possibility was checked, and there's no way to place all of them on this board. You'll see the best way to place as many as possible.
- Search stopped early: the search hit its time limit before checking everything. The moves shown are valid but may not be the best. In our testing, every board finished well within the limit.
“Best” here means best by those rules. Pieces arrive at random in the game, so no tool can promise a higher score. The solver helps you make the most of the pieces you have right now.
What the solver supports
- The classic 8 × 8 Block Blast board.
- One to three pieces, including any custom shape you draw.
- Rows and columns clearing after each move, before the next piece is placed.
Screenshot reading is in beta and may misread unusual screenshots. The solver doesn't support the game's level-based mode, and it doesn't predict scores, because the game's scoring formula hasn't been published.

Frequently asked questions
Is the Block Blast Solver free?
Yes. There's no sign-up, no account, and nothing to install.
Is there an app?
No. It's a website that works in the browser on your phone, tablet, or computer, so you can keep it open next to the game.
Can I upload a screenshot of my board?
Yes, in beta. Choose Upload screenshot above the board. The image is read on your device and never uploaded. Always compare the result with your game and fix any squares or pieces that are wrong; unclear ones are outlined.
Is every board solvable?
No. Sometimes the pieces you're given can't all fit. When that happens, the solver tells you so after checking every possibility, and shows how to place as many pieces as possible.
Why might the game behave differently from the solver?
Some Block Blast rules haven't been officially published, such as whether pieces can rotate or exactly when new pieces appear. The solver follows the most common understanding of the classic game. The Block Blast rules guide marks which rules are confirmed. If your game works differently, the suggestions may not match.
Is using a solver cheating?
Block Blast is a single-player game, so that's your call. Many people use the solver to check a tricky board or to learn why one placement works better than another.
