How to play
You complete Aquapelago when the completed grid satisfies the diagonal islands white network 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.
- Aquapelago opens from a versioned seeded position built for Nonadjacent black cells form diagonally connected numbered islands while white cells connect without a two-by-two. The independent runtime records this exact diagonal islands white network rules identity. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Aquapelago action is checked against the current board, available material, and this defining restriction: Nonadjacent black cells form diagonally connected numbered islands while white cells connect without a two-by-two. 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 Aquapelago plan is to preserve several legal continuations around Nonadjacent black cells form diagonally connected numbered islands while white cells connect without a two-by-two. The independent runtime records this exact diagonal islands white network rules identity. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Aquapelago error is to ignore the boundary rule that Nonadjacent black cells form diagonally connected numbered islands while white cells connect without a two-by-two. 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 Aquapelago, recount the remaining obligations needed until the completed grid satisfies the diagonal islands white network 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.
