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.
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.
- It only looks at your numerical rating.
- If you face a hard counter, it is pure statistical variance.
- It helps them learn before facing real humans.
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.
| Matchmaking Factor | Weight |
|---|---|
| Elo Rating | Absolute Highest Priority |
| Account Strength | The system tries to match levels, but will abandon this check if the queue takes longer than 10 seconds |
True Fairness
This is why all true esports tournaments and competitive challenges utilize the 'Tournament Standard' ruleset.
The algorithm is blind; it only respects victory.
