Nurikabe: instructions and practice
Choose a round of Nurikabe and settle into its rules. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Look at what changes after your first action. Compare the starting position with the example in the Guide. Keep the game area visible while you use its controls.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
Practice with a purpose
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. Keep the objective visible.
Understand the aim
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. An attractive position is not enough unless the goal is met. Start with a deliberate move.
A walkthrough of the rules
- 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.
Making selections and moves
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 one clear input at a time.
A closer look at one example
An island labelled 1 is already complete, so its edge neighbours must be sea. Apply the same reasoning to the position in your own round. Read the matching step again.
A common point of confusion
Two numbered islands may not merge into one. A different version of the game may use a different rule. 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.
