Description
Killer Sudoku, beautifully reimagined.
Numdoku is Killer Sudoku — the number puzzle where logic meets arithmetic. Cells are grouped into cages, each with a target sum. Fill every cage so the digits add up to the target, with no digit repeating inside the same cage. Then apply classic Sudoku elimination to complete the 9x9 grid. It's the next level of number puzzles.

WHY KILLER SUDOKU? Standard Sudoku is a classic. Killer Sudoku adds an arithmetic layer that unlocks an entirely new dimension of logic. You're not just eliminating numbers by row and column — you're reasoning about which combinations of digits can fit a cage sum, eliminating possibilities across intersecting cages, and chaining deductions that make each solve deeply satisfying.
Numdoku is that experience, polished and perfected. Download now and discover Killer Sudoku at its best.
