Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.
What you are aiming for
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Read that aim before choosing your first action. Return to the instructions when a step is unclear.
How to proceed
- 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.
Making selections and moves
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. Make sure you are interacting with the game rather than the surrounding page.
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. Notice the change in the playing area.
Watch out for this
Two numbered islands may not merge into one. Take a moment to reassess the position before continuing. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
