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.
- It only looks at your numerical rating.
- Accept the RNG.
- It helps them learn before facing real humans.
The Free-to-Play Dilemma
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.
| Matchmaking Factor | Importance Level |
|---|---|
| Elo Rating | The system will always prioritize finding an opponent within a 50-trophy range |
| King Level / Card Levels | The system tries to match levels, but will abandon this check if the queue takes longer than 10 seconds |
True Fairness
Because the ladder algorithm must balance queue times against fairness, it will never be perfectly balanced.
Trust the math, ignore the conspiracy theories, and focus on improving your own gameplay.
