About this game

Sudoku Studio is a clean, focused Sudoku puzzle game for people who just want to play. No clutter, no streak guilt, no busywork, just freshly generated puzzles and a beautiful board.

Four difficulty levels
Easy (40 clues) — gentle warm-up
Medium (32 clues) — a solid daily puzzle
Hard (26 clues) — proper challenge Impossible (22 clues) — for when you mean business

Every puzzle is unique
Each puzzle is freshly generated and proven to have exactly one valid solution. There's no fixed pool, you'll never see the same grid twice.

Never lose your progress
Your game auto-saves every second. Close the app mid-puzzle, switch tasks, get pulled away — pick up exactly where you left off, even after a phone restart.
Track your wins
A simple win counter for each difficulty level. No streaks, no daily resets, no pressure — just an honest count of puzzles solved.

Designed to stay out of your way
- Distraction-free board with a clean number pad
- Light and dark themes
- Built-in timer you can ignore if you want to - One-tap restart, instant new puzzle

Sudoku Studio is the game for people who want a working timer, a generator that respects your time, and nothing in the way.
