What is Daily Hitori?
Daily Hitori is a logic puzzle played on a grid where every cell starts with a number. Your job is to paint cells black so that no number appears more than once in any row or column — but you cannot paint freely. Black cells may never sit directly next to each other horizontally or vertically, and all the cells you leave unpainted must remain connected as one unbroken area. The result is a balancing act: every duplicate you eliminate is a cell you black out, and each blackout risks breaking the adjacency or connectivity rules. Each day brings three new puzzles, and you can choose a grid size of 8x8, 10x10, or 12x12 depending on how much of a challenge you want. A timer tracks your solving time as you work.
How Daily Hitori works
- Goal
Paint out cells so no number appears twice in any row or column while keeping black cells apart and white cells connected.
- Your moves
- Select a cell to paint it black
- Deselect a painted cell to restore its number
- Choose a grid size: 8x8, 10x10, or 12x12
- Reading the feedback
- Black cells
- Cells you have painted out; they no longer count toward row and column duplicates.
- Timer display
- Shows how long you have been working on the current puzzle.
- When a round ends
A puzzle is finished when no duplicates remain in any row or column, no black cells touch, and all white cells form one connected area.
Your first round
- Choose one of the three daily puzzles and a grid size of 8x8, 10x10, or 12x12.
- Scan the grid for numbers that repeat within a row or column — these are your painting candidates.
- Select a cell with a duplicate to paint it black, removing that number from consideration.
- Check that your new black cell is not horizontally or vertically adjacent to another black cell.
- Confirm the remaining white cells are still connected as one area.
- Continue until no duplicates remain anywhere and all three conditions hold.
Easy to miss
- Black cells may not touch horizontally or vertically — diagonal contact is fine.
- All white cells must form one connected area; a solution with duplicates gone but a split board is not valid.
- You can deselect a painted cell to bring its number back if a blackout causes problems.
