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.
Why there are six orders
Three distinct pieces have six permutations: 1 → 2 → 3, 1 → 3 → 2, 2 → 1 → 3, 2 → 3 → 1, 3 → 1 → 2, and 3 → 2 → 1. The comparison searches each order independently and ranks the resulting legal placements.
Fixed orientation and provisional strategies
Enter every piece in the orientation shown in the tray. The tool does not rotate or reflect pieces. Balanced prefers line clears before board-space metrics, while Survival gives more weight to preserving room for difficult fixed shapes.
How to read each outcome
- Complete
- All three pieces can be placed in that fixed order.
- Partial
- Only one or two pieces can be placed before the next fixed piece is blocked.
- No first move
- The first piece in that order has no legal placement on the entered board.
Replay before you place
Open a feasible order to inspect each top-left position, placed cells, cleared lines, and board after the step. Recheck the replay against the live board before making a move.
What this comparison cannot promise
It evaluates only the current board and current three fixed pieces under the selected provisional strategy. It does not know future pieces, calculate an official score or Combo formula, or guarantee a high score, win, or other live-game outcome.
