Sudoku Studio: Solve, Create, Master

Vast & Varied Puzzles

Choose from 36 variants and 1800+ built-in puzzles: Classic, Diagonal, Frame Sum, Jigsaw, Killer, Butterfly, Skyscraper, Tridoku, Honeycomb, Thermo, and more. Every 9×9 variant offers four difficulty levels—Easy, Medium, Hard, and Master—while selected variants also come in 4×4 and 16×16 sizes.

Daily & Weekly Challenges

Take on a new curated puzzle every day and keep your streak going. Each week brings a themed competition with multiple variants and a rising difficulty curve. Daily Challenge times are ranked on a global leaderboard, so you can see where you stand.

Online Co-op, Shared Solving

Play online with 2–8 players in real time on the same grid. Split the deductions, build on each other's reasoning, and see a team contribution breakdown when the puzzle is solved. If the room is full, spectators can join and watch.

Practice, Tutorial & Creation

Every variant includes a tutorial, so unfamiliar rules are easy to learn. Practice Mode lets you enter any puzzle manually and use the full toolset. Every puzzle type supports JSON import and editing, all 9×9 variants support visual editing, and your creations can be published to the Steam Workshop—or you can subscribe to puzzles from the community.

Smart Tools & Personalization

Smart notes, one-click notes, undo/redo, mistake highlighting, cell highlighting, autosave, and snapshots are all included. Play with keyboard or controller, and export any puzzle to PDF with optional progress, notes, and solution. Custom colors and randomized or looping background music are also available.

Have fun!
