## What is Killer Sudoku?

Killer Sudoku takes everything you love about classic Sudoku and adds cages: outlined groups of cells whose numbers must add up to a target sum. It is a clever blend of Sudoku and mental math, and a genuinely satisfying daily brain workout.

From the makers of Sudoku - Classic Number Puzzle.

HOW TO PLAY
Fill every row, column, and 3x3 box with the numbers 1 to 9. Cages are the groups of cells outlined with dotted lines, and the numbers inside each cage must add up to the small sum shown in its corner. Numbers cannot repeat inside a cage. Every puzzle has exactly one solution and is solvable with pure logic.

FIVE DIFFICULTY LEVELS
From Fast, for beginners still learning how cages work, up to Expert for seasoned solvers. Five carefully graded levels give a smooth learning curve without sudden jumps in difficulty.

DAILY CHALLENGE
A fresh Killer Sudoku puzzle every day. Build your streak, follow your progress on the calendar, and go back to play any day you missed.

SMART HINTS THAT TEACH
Stuck on a cage? The hint system explains the solving technique step by step, including cage sum combinations and the rule of 45, so you improve as you play. Or simply reveal the answer when you would rather keep moving.

DETAILED STATISTICS
Track your best times, win rate, and win streaks for every difficulty level, and watch your logic skills grow.

NOTES AND TOOLS
Pencil notes and fast notes mode for marking candidates
Running cage sums as you fill cells
Unlimited undo, erase, and auto-complete
Highlights for duplicate numbers and related cells
A three-mistake limit to keep you sharp

PLAYS OFFLINE
No internet connection needed. Enjoy Killer Sudoku on a plane, on the train, or anywhere you go.

Whether you are opening your first cage or hunting a new personal best on Expert, Killer Sudoku - Number Puzzle is built to be clean, fast, and quietly addictive.
