The objective of a round
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. Notice how the game responds to your input.
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. 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.
A closer look at one example
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.
Check this before moving on
Two numbered islands may not merge into one. Compare the situation with the worked example. 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.
