One thing to notice as you play
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Keep the objective visible.
Aim for this result
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. Keep the controls in easy reach.
Making your moves
- 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.
Using the playing area
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Use one clear input at a time.
See the idea in action
An island labelled 1 is already complete, so its edge neighbours must be sea. Focus on why the action is allowed, not only its outcome. Choose a deliberate next step.
A useful caution
Two numbered islands may not merge into one. Compare the situation with the worked example. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
