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.

Trophy and Rating Systems

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.
• 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.

The system will try its best to match you with someone who has the same trophies AND a similar tower level.

True Fairness

By artificially capping all card levels to a specific number, the algorithm can rely purely on the Elo rating.

The algorithm is blind; it only respects victory.
