The matchmaking algorithm is the unsung hero that determines exactly who you will face every time you press the ‘Battle’ button.

This article explores how developers design these algorithms to keep queue times short while maintaining a competitive environment.
How You Are Ranked
The algorithm’s primary goal is to match you against someone with the exact same—or very similar—trophy count.

If the system matches you perfectly, you should mathematically have a 50% chance of winning every single game you play.
Understand that a 50% win rate is normal.Queue times increase at the top of the ladder.You will eventually stabilize. The Free-to-Play Dilemma
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.

This is why all true esports tournaments and competitive challenges utilize the ‘Tournament Standard’ ruleset.

Trust the math, ignore the conspiracy theories, and focus on improving your own gameplay.
