Eight ways to solve
Explore Classic, Killer, Diagonal, Jigsaw, Hyper, Thermo, Arrow, and Kropki Sudoku. The collection includes 320 bundled puzzles across five difficulty levels: Easy, Normal, Hard, Expert, and Master.
Clear tools, fewer distractions
Enter candidates, undo or redo moves, highlight related cells, track remaining digits, and choose whether the game automatically checks entries or removes notes. Continue an unfinished puzzle through local session saving.
Make the space your own
Choose from 16 grouped static or dynamic backgrounds. Three original music tracks and 14 mixable ambient sounds create a calm setting, while reduced-motion and screen-shake options help tailor the presentation.
A focused offline collection
Play the full puzzle library offline with mouse and keyboard controls. This is a single-player collection with no online or competitive multiplayer requirement.
