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
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.Because there are fewer Grandmasters, the algorithm struggles to find perfect matches.Losing streaks are also self-correcting. 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.

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.
