Buy Sudoku Unlimited PC key

Sudoku Unlimited brings classic Sudoku and variants to a quiet garden. You can tackle a difficult deduction, practise a technique or fill in a few numbers at your own pace, progressing from small 4×4 boards to full 9×9 puzzles.

Puzzle variations

Alongside familiar rows, columns and boxes, puzzles can use irregular regions, sum cages, arrows and thermometers. Each variant adds a different rule to reason through. You can choose a puzzle style or follow the garden journey.

Learn and get help

Pencil in possibilities, undo moves or request a hint that explains the logic. Guided lessons and focused exercises let you practise techniques ranging from finding a single missing number to working through more advanced patterns. You choose how much help to use.

Find a puzzle

The game includes a daily puzzle, fresh classic boards at different difficulty levels and a separate collection of 140 puzzles. Unfinished solo puzzles save your numbers, notes and move history, so you can return to them later.

Customize the garden

Solving puzzles unlocks scenery, board palettes, music, decorations and visitors. Choose settings such as a rainy glasshouse or an autumn courtyard, select an instrumental soundtrack and mix ambient sounds. You can hide the timer while focusing on a puzzle.

Play together

Invite a friend using a room code to solve a shared board in two-player online co-op. You can compare ideas and work towards the same solution, or compete in a friendly points contest. Online play requires an internet connection; solo puzzles can be played offline.

Keep a puzzle nearby

Desktop Companion Mode displays your current puzzle in a small, resizable window beside your other apps. You can move the window, pin it on top and return to the full game while keeping your board, notes and undo history.
