If this system fails, the game becomes a frustrating, unplayable mess that bleeds players instantly.

While this conspiracy theory is widespread, the reality is much more mundane and focused entirely on mathematical fairness.

The Elo System Adapted

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.

• 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.

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.

True Fairness

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.
