Welcome to your ultimate Sudoku destination. Sudoku Studio offers a rich and endlessly engaging experience for both solvers and creators.

Vast & Varied Puzzles
Immerse yourself in a massive library. Master the classic 9x9 grid, then explore exciting variants: Diagonal, Frame, Minimax, Difference, Jigsaw, Killer, Product, XV, Butterfly, and now Skyscraper Sudoku (available in 4x4 as well). Classic and Diagonal also support 4x4 and 16x16 grids – from quick bites to epic challenges. Every variant comes with Easy, Medium, and Hard levels. Unlock the new Master difficulty for Classic and Frame Sudoku after completing 30 puzzles in each mode – the ultimate test for seasoned solvers.

Daily Challenge
Tackle a fresh curated puzzle every day. With the new Steam Daily Challenge leaderboard, compare your completion time and average solve time against players worldwide – and climb the ranks.

Practice Mode
Found right under the built‑in library, Practice Mode now supports Classic, Diagonal, and all Frame‑type variants (Frame, Minimax, Difference, and Skyscraper). Manually enter any puzzle you find and play at your own pace – the perfect sandbox for honing your skills.

Steam Workshop
Unleash your creativity with our powerful editor. Create, publish, and share your own Sudoku puzzles directly via Steam Workshop. Frame‑type variants are now fully integrated, so your custom designs can use these rules too. Subscribe to puzzles from the community, rate them, and build your following.

Smart Tools
A clean, customizable interface with multiple themes keeps you focused. Use draft marks, highlights, and error checking to refine your strategy. Save your progress anytime and resume instantly. New smart features include: one‑click auto‑fill candidates (fully undo/redo‑able), a quick‑fill shortcut (M key), candidate elimination for Killer Sudoku, and combination hints for Frame Sudoku – all designed to make logical deduction smoother and more intuitive.

Whether you're here for a mindful break, a serious brain workout, or a platform to share your passion, Sudoku Studio is your perfect puzzle haven.

Have fun!
