Take a closer look while playing
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Refer to the controls when needed.
The purpose of your moves
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Keep that objective in view throughout the round. Return to the instructions when a step is unclear.
Follow these playing steps
- 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.
Controls
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. Avoid pressing the same control repeatedly while a move is being processed.
Try this example
An island labelled 1 is already complete, so its edge neighbours must be sea. Use the example as a guide rather than a substitute for reading your board. Check the stated objective.
Avoid this misunderstanding
Two numbered islands may not merge into one. Check the rule before repeating the action. 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.
