About
milliSudoku is a clean, colorful take on the classic number puzzle - beautifully simple, endlessly replayable, and completely offline.
Every board is generated fresh on your device with exactly one solution, so there's never a guess and never a dead end. Pick your challenge, choose a look you love, and settle in.
FIVE DIFFICULTY LEVELS
Play at your pace - Trivial, Easy, Medium, Hard, or Extreme. Each step up leaves more of the grid blank for a tougher, more satisfying solve.
23 COLOR THEMES
Make every grid your own. Choose from 23 hand‑tuned palettes — from classic and vivid rainbows to soft pastels, cool blues, rich greens and purples, and fiery Lava - each with a live preview.
RANKS & BEST TIMES
Every solved puzzle earns points and climbs your rank, from Novice all the way to Yoda. Your fastest time is tracked separately for each difficulty, so there's always a record to beat.
A JOY TO PLAY
• Tap a cell, tap a number - that's it
• Correct entries lock in with a satisfying sound; wrong ones gently clear

• Win to a shower of confetti, with sound and haptic feedback along the way
