Behind the colorful graphics and intense gameplay of every successful arena battler lies a complex, invisible mathematical engine.
+
This article explores how developers design these algorithms to keep queue times short while maintaining a competitive environment.
+Trophy and Rating Systems
+
The algorithm's primary goal is to match you against someone with the exact same—or very similar—trophy count.
+
This is why winning streaks inevitably end in a 'wall' of difficult matches; the system is functioning exactly as intended.
+If you are hovering around 50%, you are in the correct arena for your skill level.Queue times increase at the top of the ladder.If you drop trophies, the algorithm matches you against easier opponents.
+The Problem of Card Levels
+
The standard Elo system works perfectly for chess because all pieces are equal, but [tower rush](https://mygit.iexercice.com/valentinacunin/tower-rush1394/wiki/How-to-Effectively-Use-Meat-Shields-in-Tower-Rush) games feature upgradeable cards.
+
The system will try its best to match you with someone who has the same trophies AND a similar tower level.

+The Esports Standard
+
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.
