How to play
You complete Cave Puzzle when all white cells form one cave, all black cells connect to the boundary as required, and every visibility clue is exact. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.
- Cave Puzzle opens from a versioned seeded position built for one orthogonally connected white cave surrounded by black rock, with each clue reporting its total visible cave length. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Cave Puzzle action is checked against the current board, available material, and this defining restriction: a clue counts itself plus uninterrupted white cells in four orthogonal directions, stopping at the first black cell or edge. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips
- A practical Cave Puzzle plan is to preserve several legal continuations around one orthogonally connected white cave surrounded by black rock, with each clue reporting its total visible cave length. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Cave Puzzle error is to ignore the boundary rule that a clue counts itself plus uninterrupted white cells in four orthogonal directions, stopping at the first black cell or edge. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
- Near the end of Cave Puzzle, recount the remaining obligations needed until all white cells form one cave, all black cells connect to the boundary as required, and every visibility clue is exact. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
