Take a closer look while playing
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Refer to the controls when needed.
What the game asks you to do
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. An attractive position is not enough unless the goal is met. Follow this game’s rules rather than another version’s.
Step by step
- 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 to use the controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. On a smaller screen, keep the active part of the board within view. Avoid pressing the same control repeatedly while a move is being processed.
See how the rules apply
An island labelled 1 is already complete, so its edge neighbours must be sea. Your next round may have a different position, so inspect it before acting. Verify the rule before continuing.
A mistake to avoid
Two numbered islands may not merge into one. A different version of the game may use a different rule. After a move, check what changed. Decide which rule explains the new state before acting again.
