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

Most modern strategy games utilize a modified version of the Elo rating system, originally designed for professional chess.

If the system matches you perfectly, you should mathematically have a 50% chance of winning every single game you play.

• There is no 'anti-deck' conspiracy.
• 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.

Maintaining Competitive Integrity

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.
