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.
How You Are Ranked
Your trophy count is a numerical representation of your skill; win a match, and you take trophies from the loser.

This is why winning streaks inevitably end in a 'wall' of difficult matches; the system is functioning exactly as intended.
Do not expect to win every game.Queue times increase at the top of the ladder.If you drop trophies, the algorithm matches you against easier opponents. Level-Based Matchmaking
The standard Elo system works perfectly for chess because all pieces are equal, but tower rush games feature upgradeable cards.

However, if no such player is available, the algorithm will prioritize queue speed over level fairness, resulting in those frustrating, mismatched games.

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

When levels are equalized, the matchmaking system shines, ensuring that the better player almost always wins.
