Sudoku+ Futoshiki & Streets

Sudoku+ – three logic puzzles in one app: Sudoku, Number Streets and Futoshiki. Play for free, puzzle and improve together.

From a child's very first number puzzles to the classic 9×9 Sudoku to brand-new challenges: Sudoku+ grows with you. Everyone in the family gets their own profile with their own avatar and their own progress – just tap and keep playing.

Three games in one app:
• Sudoku: an easy 4×4 to get started and the classic 9×9, four difficulty levels
• Number Streets: fill the white streets with consecutive numbers in any order – black cells block
• Futoshiki: every number once per row and column, and all greater/less signs must hold

Fresh puzzles every day:
• Daily puzzles in all three games, three levels each – the same for everyone. Beat your best time and earn the daily crown.

Duels & arena:
• Challenge friends on the exact same puzzle – live in real time or against the recorded best time of a pace
• Ranked duels with Elo rating in each of the three disciplines
• Watch your duel again afterwards as a real board replay and learn from it

Levels, XP & leaderboards:
• Earn experience for every puzzle you solve and level up endlessly
• Best times, trophies and leaderboards – synced across all your devices

Play together:
• Family profiles with animal avatars and separate progress
• Invite a friend – you both get bonus XP
• Share image: show off your solved dailies and your times

Fair and relaxed:
• Free to play with daily free puzzles
• Pencil notes, gentle hints and short rule intros for every game
• Anonymous usage statistics only with your consent
• Plays offline (duels need internet)

A friendly little dog joins the youngest players through the 4×4 and celebrates every solved puzzle. Perfect for a quick brain break or a cozy family puzzle night.

During our launch phase Sudoku+ is completely free – all three games, all duels, no purchase and no daily limit.

Have fun puzzling!

Small fixes in the daily puzzle

In the completion dialog the penalty time ran off the right edge of the card when the puzzle name was long. Fixed.

And when you earn the crown for the whole day, the list below now shows every puzzle of that day — before it only showed the game you happened to finish last.
