How to Play
Hitori gives you a grid filled with numbers. You must shade some cells so that no number appears more than once in any row or column. Shaded cells cannot touch orthogonally, and all unshaded cells must remain connected.
If two identical numbers are adjacent, at least one must be shaded. If a number appears three times in a row, the middle one usually stays unshaded.
Controls
Click a cell to shade it. Click again to mark it as definitely unshaded. A third click clears the mark.
Scoring
Time and accuracy are scored. Hitori rewards spotting forced shades early.
