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.
How You Are Ranked
Your trophy count is a numerical representation of your skill; win a match, and you take trophies from the loser.
When you go on a massive winning streak, your trophy count inflates, and the algorithm begins matching you against significantly better players.
- There is no 'anti-deck' conspiracy.
- With millions of players, you will occasionally draw a bad matchup.
- In the lower arenas, the system often includes 'bots'.
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.
| Matchmaking Factor | Weight |
|---|---|
| Elo Rating | 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.
