Learn the method
Play by pattern, not by keypad.
Sudoku without the typing. You mark where a candidate can live, reveal a placement when you’re sure, and let your eyes learn the pattern — not your thumbs.
The interaction
One rule: a click’s effect depends on the mode you’re in.
There is no keypad and nothing to type. Every move is positional — you point at a cell, choose what a click means in the current mode, and mark the candidate position.
- Tap a cell to choose it
- Tap a slot to mark a candidate position — a dot
- Cycle the mode to change what a tap does
Three clicks, your way.
- 1 · Dot — note where a candidate can live
- 2 · Expose — reveal a placement
- 3 · Color — your own map of the pattern
The modes
Four ways to work the grid.
The same moves, in the mode that suits you in the moment.
Dot
Note where a candidate can live — a quiet first mark, no commitment.
Expose
Reveal a placement once you’re sure. Make it count — a wrong exposure is fatal.
Color
Your own visual map of the pattern — mark by eye and see the logic stand out.
Voice
Speak your move hands-free. Every mode stays available by voice; nothing else changes.
The one hard rule
A wrong exposure is fatal — the puzzle restarts.
If you expose a placement that isn’t right, the grid fades and the puzzle begins again. Think of it as the puzzle asking you to look again — so the board teaches you the pattern instead of letting you guess your way through it.
