Description
Killer Sudoku - the ultimate number puzzle that sharpens arithmetic, logic, and focus all at once.
Unlike classic Sudoku, Killer Sudoku adds cages: groups of cells where the numbers must sum to a target value. The result is a deeper, more rewarding challenge that draws players from Sudoku, Kakuro, KenKen, Sumdoku, and Addoku. Whether you are a complete beginner or a seasoned puzzle solver, there is a difficulty level built for you.
10,000+ puzzles. Four difficulty levels. Zero filler.
HOW TO PLAY KILLER SUDOKU • Fill every row, column, and 3×3 box with digits 1-9, just like classic Sudoku • Each cage (dotted outline) has a target sum shown in the corner - hit it exactly • No digit may repeat inside a cage, row, column, or 3×3 box • Every row, column, and box always sums to 45 - use that to eliminate possibilities • Easier grids can be solved with basic arithmetic; harder ones demand advanced Sudoku techniques
KEY FEATURES • 10,000+ hand-balanced Killer Sudoku puzzles across Easy, Medium, Hard, and Extreme • Daily Challenge with a unique puzzle every day and a monthly medal tracker for streaks • Auto-solver to check or unstick yourself without losing progress • Paper-style notes for penciling in candidates • Unlimited undo so no move is ever permanent • Achievements and Leaderboards via Google Play Games • Detailed statistics: best times, streaks, and completion rates per difficulty • Multiple visual themes to match your style • Fully playable offline - no connection needed after install • Optimised for both smartphone and tablet layouts
WHO IS THIS FOR Killer Sudoku suits anyone who loves number puzzles and wants a step up from standard Sudoku. It is particularly popular with fans of Kakuro, KenKen, Sumdoku, and Addoku - the cage mechanic bridges all of these puzzle types in one clean app.
Play a puzzle a day or chase the leaderboard. Either way, your brain will thank you.

★★★★★Nyssa Eve SULLIVAN· Aug 24, 2024
Love that this version of Sudoku makes me remember my short sums from school to work out the combinations possible in answering each area missing values so have fun doin dailies
★★★★★Dennis Landman· May 16, 2023
Very Nice no constant anointing ads .great game.
★★★★☆Leonardo DiFibonacci· Oct 15, 2023
I'm enjoying this app. I usually play the extreme level which is testing enough but not so tough that it takes more than 30 minutes. The lines marking the 3 x 3 boxes could do with being more obvious.
★★☆☆☆Mattheus Bouma· Oct 17, 2023
Game does not play will. Can put any number in any box, and as long as it doesn't intersect it's ok.
★★☆☆☆Andy Hairston· Apr 2, 2025
The good: A nice interface, can be played offline, only one ad (immediately closeable) in each level, 4 different difficulty settings. The really, really bad: It only uses the *standard* Sudoku rules to determine whether a level is completed, so it's possible to ignore (or mess up) the Killer components and still get "congratulations!" for "completing" the level. I reported it a year and a half ago, but never got a response.
