Sudoku Supreme

Sudoku on PC

Sudoku Supreme is a PC Sudoku game with 200 puzzles, each with exactly one solution. You fill in the grids, using deduction to rule out numbers and work through how boxes, rows and columns affect one another.

Difficulty and rewards

Puzzles are grouped by the techniques needed to solve them. Easy puzzles use elimination; Medium puzzles require spotting interactions between boxes, rows and columns. Hard adds hidden pairs and triples, while Supreme calls for X-wings and Y-wings, with very few starting numbers. Hints per puzzle decrease by difficulty: five on Easy, three on Medium, one on Hard and none on Supreme.
