How to play
You complete Tilepaint when each block has one colour and all outside run clues describe the resulting rows and columns exactly. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.
- Tilepaint opens from a versioned seeded position built for whole outlined blocks painted black or white so every row and column clue matches its ordered runs of black cells. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Tilepaint action is checked against the current board, available material, and this defining restriction: a block cannot be split between colours; changing one cell changes every cell belonging to that outlined tile. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips
- A practical Tilepaint plan is to preserve several legal continuations around whole outlined blocks painted black or white so every row and column clue matches its ordered runs of black cells. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Tilepaint error is to ignore the boundary rule that a block cannot be split between colours; changing one cell changes every cell belonging to that outlined tile. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
- Near the end of Tilepaint, recount the remaining obligations needed until each block has one colour and all outside run clues describe the resulting rows and columns exactly. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
