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
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.
- Do not expect to win every game.
- Because there are fewer Grandmasters, the algorithm struggles to find perfect matches.
- Losing streaks are also self-correcting.
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.
| Player Perception | How it Actually Works |
|---|---|
| Rigged Matchmaking | The algorithm does not force losses; you are simply playing tilted against harder opponents because your MMR is inflated |
| The Deck Counter Code | Developers have confirmed repeatedly that the algorithm does not read the contents of your deck when finding an opponent |
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.
