A few quiet minutes. One number you're sure of. Then another. Enjoy that little rush when a puzzle that had you stumped starts to make sense. Sudoku Unlimited gives you somewhere to settle in and follow your curiosity, whether you have time for a whole board or just the next move.

Make room for a little play

Long meeting? Keep a Sudoku in the corner of your desktop and place a few numbers between the talking points. Desktop Companion Mode lets your puzzle sit beside your other apps: move it, resize it or pin it on top. When you want to sink back into the full game, your puzzle, notes and move history come with you.

Share the moment it clicks

‘I think I've found something.’ Invite a friend with a room code and work on the same board in two-player online co-op. Compare ideas, catch what the other person missed and enjoy a solution you reached together. In a competitive mood? Turn it into a friendly contest for points.

Feel yourself getting better

Start small and discover why a number belongs where it does. A guided journey through ten gardens introduces new ideas a little at a time, from your first 4×4 board to 9×9 challenges. Try out a line of thought with pencil notes and undo, and take the time to understand your next move.

Stay for one more

Return to a favourite kind of puzzle or find a new way to think. Seven styles, from familiar Classic to the extra deductions of Killer, Arrow and more, give your curiosity somewhere to go. Fresh Classic boards, a daily puzzle and a separate 140-puzzle collection keep that next discovery within reach.

Grow a place of your own

Come back to somewhere that feels like yours. Every solo puzzle brings you closer to another little discovery: a rain-soaked glasshouse, a courtyard glowing with autumn colours, a different board palette or a new piece of music. Choose the view and sounds that suit your mood, add a garden decoration or a visitor, and settle into the place you have made.

Leave the clock behind

Hide the timer, put on the gentle instrumental music and take your time. When the day calls you away, your unfinished solo puzzle saves your numbers, notes and history. Come back to the thought you left waiting.
