A fresh 4×4 every time you play.
Warm up on the small grid.
Mark a cell by pattern, not keypad — a click’s effect depends on the mode you’re in. Each 4×4 is quick, quiet, and satisfying.
- Dot — note where a candidate can live
- Expose — reveal a placement
- Color — your own map of the pattern
- A wrong exposure fades and the puzzle restarts
Free forever
