About this game

Welcome to Sudoky, the Sudoku you can play solo or share as a challenge with your friends!

A clean, fast Sudoku with no intrusive ads. Pick a difficulty, start playing and train your brain wherever you are — even offline.

KEY FEATURES

• 4 difficulty levels — from Easy to Expert, for beginners and seasoned solvers alike
• Smart hints — get a logical explanation for every move, so you learn the technique instead of just seeing the answer
• Full statistics — track your games, best times and progress
• Online leaderboard — compare your points with players around the world, weekly and all-time
• Daily challenge — a fresh puzzle every day, the same for everyone
• Challenges against friends — create a challenge, share the link and take on your friends on the same grid

PLAY AGAINST YOUR FRIENDS

Create a challenge with one tap and share it with anyone. You'll both play exactly the same puzzle at the same difficulty level. When the game ends, see in real time who scored higher and in less time. Quitting counts as a loss — so think twice before giving up!

CLEAN AND FAST INTERFACE

• Light and dark theme, for playing at night too
• Real-time conflict validation (optional)
• Pencil notes with automatic clearing
• History of your played games
• Full support for 7 languages: English, Italian, German, Spanish, Portuguese, Chinese and Japanese

PLAY OFFLINE

No connection needed for a classic game. Challenges and the leaderboard require internet, but Sudoku is always available, even in airplane mode.

TRAIN YOUR BRAIN

Sudoku is a great workout for memory, concentration and logical thinking. With Sudoky you can improve a little every day, or push yourself with the hardest levels.
