If this system fails, the game becomes a frustrating, unplayable mess that bleeds players instantly.
This article explores how developers design these algorithms to keep queue times short while maintaining a competitive environment.
The Elo System Adapted
The algorithm's primary goal is to match you against someone with the exact same—or very similar—trophy count.
When you go on a massive winning streak, your trophy count inflates, and the algorithm begins matching you against significantly better players.
- It only looks at your numerical rating.
- With millions of players, you will occasionally draw a bad matchup.
- 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.
| Algorithm Check | Significance |
|---|---|
| Elo Rating | Absolute Highest Priority |
| 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.
When levels are equalized, the matchmaking system shines, ensuring that the better player almost always wins.
