How to play Hitori
Bring your attention to one round of Hitori. Shade repeated numbers while keeping black cells separated and all white cells connected. Check the relevant rule before repeating a move. Begin with the solo mode shown on the page. Use the example below to understand a decision.
Play twelve 5×5 puzzles. Any shaded starting cells remain fixed.
Try a deliberate move
After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.
Your goal
Shade repeated numbers while keeping black cells separated and all white cells connected. An attractive position is not enough unless the goal is met. The example below illustrates a decision.
Step by step
- Click a cell to shade, mark or clear it.
- No unshaded number may repeat in a row or column.
- Black cells cannot share an edge.
- Check puzzle verifies duplicates and connectivity.
Controls
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.
A useful example
Two identical unshaded numbers in one row cannot both remain. Focus on why the action is allowed, not only its outcome. Choose a deliberate next step.
Watch out for this
Removing every duplicate can disconnect white cells. 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.
