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

This article explores how developers design these algorithms to keep queue times short while maintaining a competitive environment.
How You Are Ranked
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.
The algorithm does not care what deck you are playing.Accept the RNG.It helps them learn before facing real humans. The Problem of Card Levels
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.
Conspiracy TheoryThe Mathematical RealityRigged MatchmakingThe algorithm does not force losses; you are simply playing tilted against harder opponents because your MMR is inflatedRigged Deck MatchingDevelopers have confirmed repeatedly that the algorithm does not read the contents of your deck when finding an opponent Maintaining Competitive Integrity
This is why all true esports tournaments and competitive challenges utilize the 'Tournament Standard' ruleset.

The algorithm is blind; it only respects victory.
