Rules, controls and help for 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. Make your first input carefully and watch the result. Use the example below to understand a decision.
Play twelve 5×5 puzzles. Any shaded starting cells remain fixed.
A focus for your next round
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. Notice the feedback after each input.
Understand the aim
Shade repeated numbers while keeping black cells separated and all white cells connected. Keep that objective in view throughout the round. Check the rules when you are unsure.
From the start of a round
- 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.
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. Read a button’s label before selecting it. Avoid pressing the same control repeatedly while a move is being processed.
A closer look at one example
Two identical unshaded numbers in one row cannot both remain. Apply the same reasoning to the position in your own round. Consider the next action carefully.
A useful caution
Removing every duplicate can disconnect white cells. Read the feedback to see why an action did not have the expected result. After a move, check what changed. Decide which rule explains the new state before acting again.
