The challenge in front of you
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Use the instructions to see which actions move you towards it. Keep the controls in easy reach.
The playing sequence
- Shade sea squares and leave islands white.
- Every island contains exactly one clue.
- Different islands cannot meet along an edge.
- Check puzzle verifies sizes, connectivity and forbidden sea blocks.
How your actions work
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Contact us with the game and device if a control does not respond.
See how the rules apply
An island labelled 1 is already complete, so its edge neighbours must be sea. Compare this with the rule that governs the move. Consider the next action carefully.
Notice this detail
Two numbered islands may not merge into one. Check the rule before repeating the action. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
