Sudoku: Brain Puzzle Games brings classic Sudoku, Killer Sudoku and a new Daily Challenge together in one clean number puzzle game. Six difficulty levels take you from an easy Sudoku on a short break to expert puzzles that test real logic, and every game plays offline. Relaxing brain games with no clutter: solve at your own pace, use pencil notes and pick up any puzzle where you left off. CLASSIC SUDOKU PUZZLES • Easy, Medium, Hard, Expert, Master and Extreme levels • Every puzzle has one solution, reached by logic, never by guessing • Master and Extreme ask for advanced techniques like XYZ-Wing, W-Wing and chains • Pencil notes, hints, undo and erase whenever you need them • Play offline, no Wi-Fi needed • Light and dark mode KILLER SUDOKU A math puzzle on top of classic Sudoku. Killer Sudoku adds cages: the numbers in each cage add up to the small sum in its corner, and no number repeats inside a cage. Four levels: Easy and Medium start with numbers filled in, Hard and Expert leave it to the sums. SUDOKU RESCUE A brain puzzle for detectives. The board arrives mostly filled in and some numbers are wrong. Find the mistakes, fix them and finish the grid. Easy, Medium and Hard. HAUNTED MANOR A ghostly logic puzzle: place one ghost on every floor, in every hall and in every room, and never let two ghosts touch, not even corner to corner. No guessing, ever. DAILY SUDOKU CHALLENGE • A fresh daily puzzle every day • Build your streak and see it on your monthly calendar RANKED SUDOKU & LEADERBOARDS Play Ranked when you want a puzzle to count. Fast, clean solves raise your rating; hints and mistakes cost it. Climb through Bronze, Silver, Gold, Platinum and Diamond to Master, and compare best times with other players. TRACK YOUR PROGRESS • Best times, win rate and solved puzzles for every level • 24 achievements to earn A BRAIN GAME FOR EVERY DAY Sudoku is a number game and a brain teaser, not a memory test: every square can be worked out from the ones around it. A few minutes of puzzle games on the bus, on a coffee break or before bed gives your mind something to work on. HOW TO PLAY SUDOKU Fill the 9×9 grid so every row, column and 3×3 box holds the numbers 1 to 9 exactly once. Play as a guest, no account needed. Sign in to back up your progress, sync your devices and join the leaderboards.
