Behind the colorful graphics and intense gameplay of every successful arena battler lies a complex, invisible mathematical engine.

Many players believe that matchmaking is intentionally rigged against them, constantly forcing them to fight 'hard counters' after a win streak.
The Elo System Adapted
Your trophy count is a numerical representation of your skill; win a match, and you take trophies from the loser.

If the system matches you perfectly, you should mathematically have a 50% chance of winning every single game you play.
If you are hovering around 50%, you are in the correct arena for your skill level.Because there are fewer Grandmasters, the algorithm struggles to find perfect matches.You will eventually stabilize. The Free-to-Play Dilemma

By artificially capping all card levels to a specific number, the algorithm can rely purely on the Elo rating.
