How to play Hitori

Make Hitori your next activity in the game library. Shade repeated numbers while keeping black cells separated and all white cells connected. Look at what changes after your first action. Check the rule that explains your first action. Keep the game area visible while you use its controls.

Play twelve 5×5 puzzles. Any shaded starting cells remain fixed.

A careful first round

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Keep the objective visible.

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. Return to the instructions when a step is unclear.

Step by step

1. Click a cell to shade, mark or clear it.
2. No unshaded number may repeat in a row or column.
3. Black cells cannot share an edge.
4. 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. A new-round button replaces the current round.

A useful example

Two identical unshaded numbers in one row cannot both remain. Use the example as a guide rather than a substitute for reading your board. Read the matching step again.

Watch out for this

Removing every duplicate can disconnect white cells. A different version of the game may use a different rule. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
