Daily Sudoku
Every day at midnight, all players receive the same new puzzle. Daily Sudoku is a shared challenge: solve exactly the same puzzle as everyone else and compare your time with friends and family. It is free and ready whenever you are.
The difficulty changes from day to day, giving you both quick and demanding sessions throughout the week. Some days you will finish during a coffee break; on others, you will need more advanced techniques.
How the daily challenge works
A new puzzle is published every day at midnight local time in Norway. Players around the world all receive the same puzzle, which can be played only on that day. Complete it, and the day counts toward your streak.
Because everyone solves the same puzzle, the daily challenge becomes a real competition. Share your time with friends and see who finishes the puzzle fastest, or use it as your own daily training session.
Keep your streak alive
Your streak counts how many consecutive days you have completed the daily challenge. If you miss a full day, the count starts over. Many players use their streak to build a daily habit: one puzzle a day keeps the mind active and the statistics moving.
You can play as a guest, but a free account saves your streak, times and progress across devices. That way, you will not lose anything when switching between your phone and computer.
Techniques that get you through the week
Because the difficulty varies, a broad range of skills is useful. These techniques cover most of what you will encounter in the daily challenge, and each has its own page with interactive examples.
