Sudoku Prime: Number Puzzle

Premium Sudoku: no ads, no tracking, we never sell your data. Includes a Coach that teaches eleven techniques, seven variants.

Sudoku, properly. No ads, no data sold, no tracking at all.

Sudoku Prime is the Sudoku app for people who actually want to get better at Sudoku. Seven variants in one premium app, Classic 9×9, Mini 4×4 and 6×6, X-Sudoku with diagonals, Hyper with overlap regions, Jigsaw with irregular pieces, and Killer with cage sums. Nothing else to install.

A hint coach that teaches.

The built-in Coach doesn't just hand you the answer. Three escalating tiers: a nudge toward the right region, a spotlight on the candidate cells, then a full step-by-step explanation of the technique — naked singles, hidden pairs, X-Wings, Y-Wings, Swordfish, eleven techniques in total. You still place the digit yourself.

Every day, same puzzle, everyone in the world.

The daily puzzle is identical for every player. Compete on a global Game Center leaderboard, keep streaks, see your best and average times. Or invite a friend to race the exact same grid via a deep link in Messages — same seed, same difficulty, side-by-side stats.

Built for the long haul.

Universal app for iPhone and iPad. Game Center, iCloud sync, full VoiceOver support with custom rotors for mistakes and single candidates. Dynamic Type capped at xxxLarge. Reduce Motion honored everywhere. Color-blind-safe mistake markers.
