Games Like Sudoku Unlimited

Sudoku Unlimited brings classic Sudoku and inventive variants to a quiet garden. Take on a difficult deduction, learn a new technique or fill in a few numbers on a short break. Play at your own pace, with room to grow.

One grid, new ways to think

Start with familiar rows, columns and boxes, then explore irregular regions, sum cages, arrows and thermometers. Each variant adds a different rule to reason with. Choose the puzzle style you enjoy, or follow the garden journey from small 4×4 boards to full 9×9 challenges.

Understand your next move

Pencil in possibilities, undo a move and ask for a hint that explains the logic. Guided lessons and focused exercises help you practise techniques, from spotting a single missing number to working through more advanced patterns. The tools are there when you want them; you decide how much help to use.

Find your next puzzle

Return for the daily puzzle, generate fresh classic boards at different difficulty levels or work through the separate 140-puzzle collection. Switch between a quick session and a longer challenge without losing your place: unfinished solo puzzles save your numbers, notes and move history.

Make the garden yours

Solving puzzles unlocks scenery, board palettes, music, decorations and visitors. Settle by a rainy glasshouse or an autumn courtyard, choose your instrumental soundtrack and mix ambient sounds to suit the scene. Hide the timer when you want to focus on the puzzle.

Solve together

Invite a friend with a room code and share one board in two-player online co-op. Compare ideas and work towards the same solution, or try a friendly points contest. Online play requires an internet connection; solo puzzles can be played offline.

Keep a puzzle close

Desktop Companion Mode puts your current puzzle in a small, resizable window beside your other apps. Move it, pin it on top and return to the full game whenever you like. Your board, notes and undo history come with you.
