What it does
You copy your current board and the pieces you've been given, and the solver shows you a step-by-step plan for placing them: which piece to place first, exactly where it goes, and which rows or columns clear along the way.
How you use it
- Tap the squares on the 8 × 8 board that are filled in your game. You can drag to fill several at once.
- Add up to three pieces exactly as they appear in the game. If a shape isn't in the list, you can draw it.
- Press Solve, then step through the moves.
You can also start from a screenshot of your game (beta). The board and pieces are read on your device, and you check and correct them before solving. Open the solver to try it.
How it works
The solver tries every order of your pieces and every position where each one fits, clearing full rows and columns after each move, just as the game is commonly described. It then ranks the possibilities: first by how many pieces it can place, then by how many lines it clears, and finally by how open the board is left, favoring room for large pieces and avoiding boxed-in single squares.
All of this runs in your web browser, on your own device. Your board and pieces are never sent to a server.
What the results mean
- All pieces fit: every possibility was checked, and the plan shown is the best one according to the ranking above.
- These pieces can't all fit: every possibility was checked, and there's no way to place all of them. The solver shows how to place as many as possible.
- Search stopped early: the search hit its time limit. The moves shown work, but they may not be the best.
Limitations
- Some of the game's rules haven't been officially published, such as whether pieces can rotate. The solver follows the most common understanding of the classic game. The rules guide shows which rules are confirmed.
- “Best” means best by the solver's ranking. Pieces arrive at random, so no tool can guarantee a score.
- Screenshot reading is in beta. It's been tested on sample images, not yet on a wide range of real game screenshots, so always compare the result with your game.
- It doesn't support the game's level-based mode or calculate points.
