The matchmaking algorithm is the unsung hero that determines exactly who you will face every time you press the 'Battle' button.
Many players believe that matchmaking is intentionally rigged against them, constantly forcing them to fight 'hard counters' after a win streak.
How You Are Ranked
Most modern strategy games utilize a modified version of the Elo rating system, originally designed for professional chess.
When you go on a massive winning streak, your trophy count inflates, and the algorithm begins matching you against significantly better players.
- The algorithm does not care what deck you are playing.
- With millions of players, you will occasionally draw a bad matchup.
- AI opponents ensure instant queue times for beginners.
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 | Significance |
|---|---|
| Current Rank | Absolute Highest Priority |
| Upgrade Status | Secondary Priority |
True Fairness
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.
