The Hitori playbook
Choose a round of Hitori and settle into its rules. Shade repeated numbers while keeping black cells separated and all white cells connected. Check the relevant rule before repeating a move. Use the opening round to become familiar with the layout. Look at what changes after your first action.
Play twelve 5×5 puzzles. Any shaded starting cells remain fixed.
Something to practise
After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.
The goal to keep in mind
Shade repeated numbers while keeping black cells separated and all white cells connected. Read that aim before choosing your first action. Notice how the game responds to your input.
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.
The controls to know
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. Look at the feedback after the action.
A useful example
Two identical unshaded numbers in one row cannot both remain. Compare this with the rule that governs the move. Read the matching step again.
One detail worth checking
Removing every duplicate can disconnect white cells. Check the rule before repeating the action. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
