Block Blast solver
Updated October 24, 2026 · Free, no sign-up
Stuck on a board? Tap the filled squares to copy your board, pick the three pieces you were dealt, and the solver shows the best order and where to put each one, with the lines it clears.
How to use the solver
- Copy your board. Tap each filled square, or drag across several. Tap again to empty a square.
- Pick your pieces. Tap the three shapes you were dealt, in any order; they fill slots 1, 2 and 3.
- Solve. You get one small board per move: the coloured piece is where it goes, in that order.
How the solver picks the best move
It tries every order of your three pieces and every spot each one fits, clearing full rows and columns after each move just like the game. Among the lines that place all three pieces, it prefers the one that clears the most lines, with a bonus for clearing on consecutive moves, then the one that leaves the board most open: plenty of empty squares, no single trapped holes, and room for the big 3×3 square.
Block Blast tips the solver follows
- Always keep room for the 3×3. It is the piece that ends most games; a free 3×3 area is worth more than a few points now.
- Never leave single holes. A one-square gap surrounded on all sides only fits the 1×1 piece.
- Think about the order. Place the piece that completes a line first, so the clear makes room for the others.
- Build along the edges. Filling from the sides keeps the middle open for any shape.

Questions
How does the Block Blast solver work?
You copy your board and your three pieces. The solver tries every order of the pieces and every position on the board, clears full rows and columns after each move as the game does, and keeps the line that clears the most and leaves the most open, playable board.
Is using a solver cheating?
Block Blast is a single-player game with no money on the line, so most players use a solver to learn: seeing why a move is best is how you get better at spotting it yourself. Use it on the boards that stump you.
Why does the order of the pieces matter?
A piece can complete a line that frees room for the next one. Placing the same three pieces in a different order can be the difference between clearing two lines and having nowhere to put the last piece.
Does it work for Blockblast on Android and iPhone?
Yes. Block Blast (often searched as Blockblast) plays the same on both, so the solver works for either: open this page in your phone browser, copy your board and pieces, and play the moves it shows.
What if no piece fits?
Then the board is game over, and the solver tells you. If only some pieces fit, it shows the order that places as many as possible.
Is this made by the makers of Block Blast?
No. Block Blast is a game by Hungry Studio; this free helper is made by Rekto Digital, the studio behind Plonk, a calm block puzzle game for Android.
