How to play
You complete Heteromino when the completed grid satisfies the oriented triomino partition 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.
- Heteromino opens from a versioned seeded position built for The board is partitioned into triominoes; adjacent triominoes cannot share both shape and orientation. The independent runtime records this exact oriented triomino partition rules identity. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Heteromino action is checked against the current board, available material, and this defining restriction: The board is partitioned into triominoes; adjacent triominoes cannot share both shape and orientation. 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 Heteromino plan is to preserve several legal continuations around The board is partitioned into triominoes; adjacent triominoes cannot share both shape and orientation. The independent runtime records this exact oriented triomino partition rules identity. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Heteromino error is to ignore the boundary rule that The board is partitioned into triominoes; adjacent triominoes cannot share both shape and orientation. 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 Heteromino, recount the remaining obligations needed until the completed grid satisfies the oriented triomino partition 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.
