A small practice goal
Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Notice the feedback after each input.
Understand the aim
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. The feedback beside the game helps you follow the round. Keep the controls in easy reach.
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.
Getting comfortable with 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. Use the control method described here for this activity. Check any mode label before starting.
One way to understand the rules
An island labelled 1 is already complete, so its edge neighbours must be sea. Compare this with the rule that governs the move. Keep the controls nearby.
One detail worth checking
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.
