Understand the move, not just the answer

Survival
After completing as many pieces as possible, compare difficult-shape fits and connected open space before line clears.
Evidence, not a score promise
How the search earns its answer
The search runs in a local Web Worker so the interface can stay responsive while it examines all six original piece orders and every legal top-left placement.
Exhaustive current tray
Every legal sequence for the three pieces is evaluated; identical outcomes are ranked deterministically by the selected provisional profile.
Seeded replay checks
The legality engine passed 10,000 seeded legality replays that independently replayed every returned move.
Independent comparisons
The optimized search also matched 500 independent dense-board comparisons.
Current limits
Known limits
- Screenshot recognition may miss unfamiliar themes, crops, or device layouts; review the editable draft or use Manual input.
- Pieces stay in the fixed orientation you enter; the solver does not rotate or reflect them.
- The search considers only the current three pieces, not a future tray.
- Line-clear and refresh behavior follows a provisional rule profile that may differ from the live game.
- No result guarantees a live score, Combo, or future tray.
Quick answers
Frequently asked questions
Is the solver free?
Yes. The local solver is free to use, with no account required.
Can I upload a screenshot?
Yes. Choose, drop, or paste a screenshot, or use Manual input. The image is decoded locally in your browser and the recognized draft remains editable.
Why must I review screenshot recognition?
Game themes, crops, and device layouts vary. Review every occupied cell and fixed piece before choosing Confirm & Solve, or switch to Manual input if the draft is unclear.
Does the solver guarantee a score or future result?
No. It compares legal moves for the current board and three pieces under a provisional rule profile; it cannot guarantee a live score, Combo, refresh behavior, or a future tray.
What does Continue Next Round do?
After a complete result, it keeps the final board, clears the three piece editors, and lets you enter the next tray.
What boards and pieces are supported?
The solver supports one 8×8 board and the current three fixed-orientation pieces you enter. It does not plan across later trays.
