Behind the colorful graphics and intense gameplay of every successful arena battler lies a complex, invisible mathematical engine.

While this conspiracy theory is widespread, the reality is much more mundane and focused entirely on mathematical fairness.
How You Are Ranked
Most modern strategy games utilize a modified version of the Elo rating system, originally designed for professional chess.

This is why winning streaks inevitably end in a 'wall' of difficult matches; the system is functioning exactly as intended.
Understand that a 50% win rate is normal.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.

However, if no such player is available, the algorithm will prioritize queue speed over level fairness, resulting in those frustrating, mismatched games.

Because the ladder algorithm must balance queue times against fairness, it will never be perfectly balanced.

The algorithm is blind; it only respects victory.
