About Sudoku — Killer & Daily Puzzle
The Sudoku app that gives you more — not fewer ads.
While competitors charge just to remove ads, ours has none. Never has.
Premium unlocks more game: Killer Sudoku, Coach hints, advanced
themes, and tools that make you a better solver.
FOUR WAYS TO PLAY
Classic 9×9
The timeless puzzle. Fill every row, column, and 3×3 box
with digits 1–9. Every puzzle has exactly one solution.
Sudoku X
Both long diagonals must also contain 1–9. One extra
constraint that changes every strategy.
Killer Sudoku Premium
No given digits. Cages show you the target sum — you work
out where every digit goes from pure logic alone.
Mini 6×6 Premium
Fast, satisfying puzzles on a 6×6 grid. Perfect for
a three-minute break.
SIX DIFFICULTY LEVELS
Easy · Medium · Hard · Expert · Master · Extreme
Only 17 starting clues on Extreme. No guessing — just logic
pushed to its limit.
DAILY CHALLENGE & STREAKS
A fresh puzzle every day. Build a streak, earn trophies,
and replay any past daily from the calendar archive.
Streak freezes replenish monthly so a busy day
doesn't erase your chain.
