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.
If the system matches you perfectly, you should mathematically have a 50% chance of winning every single game you play.
- The algorithm does not care what deck you are playing.
- Accept the RNG.
- AI opponents ensure instant queue times for beginners.
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.
| Algorithm Check | Significance |
|---|---|
| Current Rank | Absolute Highest Priority |
| Account Strength | The system tries to match levels, but will abandon this check if the queue takes longer than 10 seconds |
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.
