THE PLAYBOOK · ZZBSDZ
Getting started with Nurikabe
Use a short break to learn the rhythm of Nurikabe. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Use the example below to understand a decision. Use the opening round to become familiar with the layout. Choose a clear next step rather than rushing through the instructions.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
A focus for your next round
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Make the next step deliberately.
Understand the aim
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Use the instructions to see which actions move you towards it. Notice how the game responds to your input.
The steps to 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. Use the visible help when you are unsure of the next input.
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. Consider the next action carefully.
Check this before moving on
Two numbered islands may not merge into one. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
