How to play
You complete Pentominous when the completed grid satisfies the adjacent distinct pentominoes constraint set, every fixed clue, and the profile's whole-board completion test. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.
- Pentominous opens from a versioned seeded position built for The grid is partitioned into pentominoes; edge-adjacent pentominoes differ up to rotation and reflection, and shape clues bind regions. The independent runtime records this exact adjacent distinct pentominoes rules identity. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Pentominous action is checked against the current board, available material, and this defining restriction: The grid is partitioned into pentominoes; edge-adjacent pentominoes differ up to rotation and reflection, and shape clues bind regions. Partial assignments remain legal only while at least one completion still satisfies those constraints. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips
- A practical Pentominous plan is to preserve several legal continuations around The grid is partitioned into pentominoes; edge-adjacent pentominoes differ up to rotation and reflection, and shape clues bind regions. The independent runtime records this exact adjacent distinct pentominoes rules identity. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Pentominous error is to ignore the boundary rule that The grid is partitioned into pentominoes; edge-adjacent pentominoes differ up to rotation and reflection, and shape clues bind regions. Partial assignments remain legal only while at least one completion still satisfies those constraints. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
- Near the end of Pentominous, recount the remaining obligations needed until the completed grid satisfies the adjacent distinct pentominoes constraint set, every fixed clue, and the profile's whole-board completion test. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
