Sudoku Mission: Number Game

Sudoku that respects your time and your intelligence. Buy it once, play forever

- no adverts, no in-app purchases, no account, and no internet connection

required.

FIVE TIERS THAT MEAN SOMETHING

Easy through Evil are not guesses. Every puzzle is solved by an engine that

uses real human techniques - naked and hidden singles, locked candidates,

pairs and triples, X-Wing, XY-Wing, Swordfish - and graded by what it actually

takes a person to see. A short puzzle hinging on one X-Wing is not "easy" just

because it is short.

A DAILY CHALLENGE EVERYONE SHARES

One board a day, identical for every player, ramping from Monday Easy to Sunday

Evil. Build a streak, collect medals on the calendar, and compare your time

against par.

HINTS THAT TEACH

Stuck? A hint explains the deduction - "R4C7 is the only cell in box 6 that can

hold 8" - instead of just filling in the answer. You finish the puzzle having

learned the pattern.

CLIMB THE RANKS

Bronze to Grandmaster. Your rating reflects recent form rather than hours

logged, so the badge says how you are playing now. Points bank permanently,

medals are awarded against a per-difficulty par time, and 18 achievements track

the milestones.
