Why Matchmaking Algorithms are So Important in Tower Rush
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.
Most modern strategy games utilize a modified version of the Elo rating system, originally designed for professional chess.
When you go on a massive winning streak, your trophy count inflates, and the algorithm begins matching you against significantly better players.
The standard Elo system works perfectly for chess because all pieces are equal, but tower rush games feature upgradeable cards.
However, if no such player is available, the algorithm will prioritize queue speed over level fairness, resulting in those frustrating, mismatched games.
| System Priority | Importance Level |
|---|---|
| Current Rank | The system will always prioritize finding an opponent within a 50-trophy range |
| Account Strength | The system tries to match levels, but will abandon this check if the queue takes longer than 10 seconds |
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.
