About the Game

Take your time. Find the next digit.

Start with classic Sudoku, then explore thermometers, arrows, cages and more. Infinite Sudoku brings twenty rule sets into one warm, quiet puzzle room. Choose a variant and solve at your own pace.

Twenty variants. Five difficulty levels.

Classic, Diagonal, Jigsaw, Hyper, Odd/Even, Killer, Thermometer, Arrow, Sandwich, Kropki, XV, Samurai, Anti-Knight, Anti-King, Nonconsecutive, German Whispers, Renban, Palindrome, Little Killer and Skyscraper.
Choose from Beginner, Easy, Standard, Hard and Challenge. Illustrated rules and a replayable, hands-on tutorial introduce filling cells, notes, undo and hints.

Candidate diagrams and short explanations point to evidence on the grid. You decide whether to enter the suggested digit. A direct cell hint is also available. Assistance is recorded; complex positions may need deeper analysis, and the assistant cannot always find the next logical step.
