Understand the basics of Hitori

Give this approach a try

Read one step at a time and try it on the playing area. Match the instruction to the control you use. Keep the objective visible.

Your objective

Shade repeated numbers while keeping black cells separated and all white cells connected. An attractive position is not enough unless the goal is met. Check the rules when you are unsure.

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.

Using the playing area

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Return to the rules if the result is unexpected.

Put the rules into context

Two identical unshaded numbers in one row cannot both remain. Your next round may have a different position, so inspect it before acting. Keep the game’s format in mind.

One detail worth checking

Removing every duplicate can disconnect white cells. Take a moment to reassess the position before continuing. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
