Order matters
See why checking all six piece orders can preserve a complete sequence.
Partial
Honest partial result
Inspect the longest legal prefix when all three pieces cannot fit.
Enter the board and current tray
Tap or click a board cell to mark it filled. On a computer, you can drag across cells or use the keyboard to focus a cell and toggle it. Row 1 is the top row, so enter the board in the same orientation you see on screen.
Enter exactly three current pieces. Pieces stay in their displayed fixed orientation: the solver does not rotate or reflect them automatically.
Presets and 5×5 custom entry
Use a preset when it matches a current piece exactly. Otherwise, draw the piece in its 5×5 editor, preserving its visible top-row orientation. Clear or replace each piece until all three editors match the tray.
Confirm before calculating
Confirmation checks that the board is 8×8 and that all three pieces are non-empty. It is the moment to compare the entered cells with your current game before the solver searches the legal move sequence.
Read the result honestly
- Complete
- All three current pieces have a legal sequence under the selected strategy.
- Partial
- One or two pieces can be placed, but no sequence places the entire current tray.
- No first move
- None of the three entered pieces fits the board as it is now.
8×8 input boundary
This tool evaluates one clear 8×8 board and the three pieces currently in the tray. It does not model a differently sized layout, future pieces, rotation controls, game scoring rules, or live game state.
