How to play Hitori
Use a short break to learn the rhythm of Hitori. Shade repeated numbers while keeping black cells separated and all white cells connected. Keep the game area visible while you use its controls. Read the objective before making your first input. Check the relevant rule before repeating a move.
Play twelve 5×5 puzzles. Any shaded starting cells remain fixed.
Focus on one rule
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Refer to the controls when needed.
Your goal
Shade repeated numbers while keeping black cells separated and all white cells connected. The feedback beside the game helps you follow the round. Start with a deliberate move.
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. On a smaller screen, keep the active part of the board within view. Return to the rules if the result is unexpected.
A useful example
Two identical unshaded numbers in one row cannot both remain. Focus on why the action is allowed, not only its outcome. Look for the relevant detail.
Watch out for this
Removing every duplicate can disconnect white cells. Compare the situation with the worked example. 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.
