Your Global Player Rating
One of the most innovative features of Sudoku Global is the personal player rating system — a sophisticated, dynamic score that reflects your true Sudoku abilities across all game modes. Unlike simple win-loss records or total puzzle counts, your player rating uses advanced algorithms to evaluate the difficulty of puzzles you solve, the speed at which you complete them, and your performance in competitive matches and tournaments.
Think of it like the rating systems used in Chess or competitive video games, but specifically calibrated for Sudoku. When you solve a difficult puzzle quickly, your rating increases significantly. When you win battles against higher-rated opponents, you gain more rating points. When you perform well in tournaments against skilled players, your rating jumps accordingly. This creates a fair, meaningful measure of skill that goes beyond simple metrics.
Track your progress over weeks and months with detailed statistics and beautiful visualizations that show your rating trajectory. See exactly when you improved, identify which difficulty levels you excel at, and understand which aspects of your game need more practice. Your rating becomes a personal benchmark — a number that represents your Sudoku mastery and gives every game meaningful stakes. Watch it climb from beginner levels into intermediate ranges and eventually, with dedication and practice, toward expert and master tiers. The rating system ensures that no matter your skill level, you'll always have goals to chase and progress to celebrate.

Real-Time Battle Mode
The Battle Mode is where Sudoku Global truly shines as a competitive experience.

The first player to correctly complete the puzzle wins the match, earning rating points and the satisfaction of outthinking and outpacing their opponent.
Battle Mode transforms solitary puzzle-solving into an exhilarating competitive sport. The psychological element adds a thrilling dimension — managing time pressure, maintaining accuracy under stress, and knowing that somewhere out there, your opponent is frantically working through the same puzzle creates an intensity that traditional Sudoku simply cannot match.
