Behind the colorful graphics and intense gameplay of every successful arena battler lies a complex, invisible mathematical engine.
Many players believe that matchmaking is intentionally rigged against them, constantly forcing them to fight 'hard counters' after a win streak.
The Elo System Adapted
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.

- Understand that a 50% win rate is normal.
- Patience is required.
- If you drop trophies, the algorithm matches you against easier opponents.
The Problem of Card Levels
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 | Importance Level |
|---|---|
| Trophy Count | Absolute Highest Priority |
| King Level / Card Levels | The system tries to match levels, but will abandon this check if the queue takes longer than 10 seconds |
Maintaining Competitive Integrity
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.
