The essentials of playing Nurikabe
Read the aim of Nurikabe, then make your first move. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Choose a clear next step rather than rushing through the instructions. Make your first input carefully and watch the result. Use the example below to understand a decision.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
Build familiarity through play
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Notice the feedback after each input.
What counts as success
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. Check the rules when you are unsure.
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.
Your inputs
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. On a smaller screen, keep the active part of the board within view. Use the visible help when you are unsure of the next input.
An example to follow
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. Choose a deliberate next step.
Notice this detail
Two numbered islands may not merge into one. Check the rule before repeating the action. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
