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
Your trophy count is a numerical representation of your skill; win a match, and you take trophies from the loser.
If the system matches you perfectly, you should mathematically have a 50% chance of winning every single game you play.
- It only looks at your numerical rating.
- Accept the RNG.
- It helps them learn before facing real humans.
Level-Based Matchmaking
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 | Significance |
|---|---|
| Current Rank | 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.
