An idea for your next attempt
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Use the example to check your reasoning.
Your objective
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.
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.
Input guidance
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. Return to the rules if the result is unexpected.
Work through an 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. Verify the rule before continuing.
Watch out for this
Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. After a move, check what changed. Decide which rule explains the new state before acting again.
