Nine — Sudoku, No Ads
Coming soon to the App Store for iPhone.
No ads. Ever. No banners, no pop-ups, no videos between puzzles — not even in the free version.
Every puzzle has exactly one solution and is checked by a solver before you see it, so you never have to guess. Difficulty is graded by the techniques you'll need — from singles on Easy to pairs, triples and X-Wings on Expert.
