## What is Tertiary Sudoku?

Tertiary Sudoku is a clean, offline number-puzzle game for players aged 14 and up. Every puzzle is generated on your device with a guaranteed unique solution, so you never run out and never see the same grid twice. Choose from four difficulty levels - Easy, Medium, Hard, and Expert - and solve at your own pace.

- Four difficulty levels, from gentle warm-ups to ruthless Expert grids
- Smart hints whenever you ask - reveal the right number for any cell
- Pencil notes (candidates) with optional auto-cleanup
- Conflict and same-number highlighting you can toggle on or off
- Optional 3-strike challenge mode for mistake-free runs
- A timer, scoring, and full game history kept entirely on your iPhone
- Stats tab with your best times and scores per difficulty
- Feedback and About tabs built right in
- 100% offline and private - nothing ever leaves your device

Track your best times and scores per difficulty, resume any game you leave, and train your brain one grid at a time.
