About this game

Sharpen your mind with Splendid Killer Sudoku — the number puzzle with a twist.

Killer Sudoku combines the logic of classic Sudoku with the challenge of cage sums. Fill the grid so every row, column, and box contains each number once — but here's the twist: dashed "cages" group cells together, and the numbers inside each cage must add up to its target sum, with no repeats. It's Sudoku, evolved.
