To start a new game, press the menu button in the top-right corner of the window, and select New Game. If you are already playing a game, Hitori will ask if you want to stop the current game.

Par scrivi une casele, fâs clic parsore di une; par scancelâle, fâs clic parsore di chê di gnûf. Cuant che lis caselis a vegnin scritis siche nissune des trê regulis a vegnin violadis, il zûc al finìs e la taule no pues jessi plui modificade.

Hitori also allows you to tag cells for your own reference when solving a board. This can be achieved by holding Ctrl or Shift and clicking on a cell. They both tag cells differently, and cells can be tagged in both manners at the same time. Tagged cells can be un-tagged by clicking on them again while holding either Ctrl or Shift again.

To undo or redo a move, press Undo or Redo in the header bar. You may undo or redo as many moves as you like without restriction.

To get a hint on which cells to paint out, press Hint in the header bar. A cell will be hinted with a flashing red outline. This shows that the current status of the cell (painted or unpainted) is incorrect, and should be changed for the game to be won.
