About
Sudoku Champions puts you in the arena.
This isn't solitaire Sudoku. In Ranked mode, you face off against an opponent in real time. You both
get the exact same puzzle at the exact same moment. First one to finish wins. Your Elo rating goes up
or down based on the result - just like competitive chess.
Play 5 placement matches to find your starting rank, then grind your way from Bronze through Silver,
Gold, Platinum, Diamond, Master, and all the way to Grandmaster. Every match counts.
FOUR WAYS TO PLAY
Ranked
The main event. 1v1 matches where speed and accuracy both matter. Watch your opponent's progress bar
creep forward while you work. Win and climb. Lose and learn.
Daily Challenge
A fresh puzzle drops every day. Complete it to keep your streak alive. Miss a day and you're back to
zero.
Story Mode
10 chapters of hand-picked puzzles that get harder as you go. Work through them at your own pace and
unlock achievements along the way.
Practice
No pressure, no opponent. Five difficulty levels from Easy to Master. Great for warming up or trying
new techniques.
