Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
Something to practise
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.
The objective of a round
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. Keep the controls in easy reach.
From the start of a round
- 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

See the idea in action
An island labelled 1 is already complete, so its edge neighbours must be sea. Your next round may have a different position, so inspect it before acting. Keep the controls nearby.
Check this before moving on
Two numbered islands may not merge into one. Check the rule before repeating the action. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
