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
The algorithm's primary goal is to match you against someone with the exact same—or very similar—trophy count.
This is why winning streaks inevitably end in a 'wall' of difficult matches; the system is functioning exactly as intended.
- The algorithm does not care what deck you are playing.
- With millions of players, you will occasionally draw a bad matchup.
- 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.
To combat this, developers have implemented secondary checks that look at the player's King Tower level.
| Conspiracy Theory | How it Actually Works |
|---|---|
| Forced Loss Streaks | The algorithm does not force losses; you are simply playing tilted against harder opponents because your MMR is inflated |
| Rigged Deck Matching | Developers have confirmed repeatedly that the algorithm does not read the contents of your deck when finding an opponent |
The Esports Standard
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.
