Why Matchmaking Algorithms Are So Important In Tower Rush

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.

The Elo System Adapted

Most modern strategy games utilize a modified version of the Elo rating system, originally designed for professional chess.


When you go on a massive winning streak, your trophy count inflates, and the algorithm begins matching you against significantly better players.

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.You will eventually stabilize.
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.

The Esports Standard

Because the ladder algorithm must balance queue times against fairness, it will never be perfectly balanced.


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