Hitori: a guide for your next round

Try Hitori at your own pace and keep its objective in view. Shade repeated numbers while keeping black cells separated and all white cells connected. Use the example below to understand a decision. Begin with the solo mode shown on the page. Check the relevant rule before repeating a move.

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

Practice with a purpose

Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Keep the objective visible.

What the game asks you to do

Shade repeated numbers while keeping black cells separated and all white cells connected. Read that aim before choosing your first action. Take a moment to understand the current position.

Making your moves

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.

How your actions work

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Look at the feedback after the action.

Try this example

Two identical unshaded numbers in one row cannot both remain. Your next round may have a different position, so inspect it before acting. Notice the change in the playing area.

Keep this in mind

Removing every duplicate can disconnect white cells. Compare the situation with the worked example. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
