The matchmaking algorithm is the unsung hero that determines exactly who you will face every time you press the 'Battle' button.
While this conspiracy theory is widespread, the reality is much more mundane and focused entirely on mathematical fairness.

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.
- If you are hovering around 50%, you are in the correct arena for your skill level.
- Queue times increase at the top of the ladder.
- Losing streaks are also self-correcting.
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.
The system will try its best to match you with someone who has the same trophies AND a similar tower level.
| Algorithm Check | Weight |
|---|---|
| Elo Rating | The system will always prioritize finding an opponent within a 50-trophy range |
| Upgrade Status | The system tries to match levels, but will abandon this check if the queue takes longer than 10 seconds |
The Esports Standard
By artificially capping all card levels to a specific number, the algorithm can rely purely on the Elo rating.
The algorithm is blind; it only respects victory.
