Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
Practice beyond the first move
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Notice the feedback after each input.
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. Review the board or playing area as it changes.
The order of play
- 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. Use the control method described here for this activity. A new-round button replaces the current round.
One way to understand the rules
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 game’s format in mind.
Where a round can go wrong
Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. 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.
