The matchmaking algorithm is the unsung hero that determines exactly who you will face every time you press the 'Battle' button.

This article explores how developers design these algorithms to keep queue times short while maintaining a competitive environment.

How You Are Ranked

The algorithm's primary goal is to match you against someone with the exact same—or very similar—trophy count.

When you go on a massive winning streak, your trophy count inflates, and the algorithm begins matching you against significantly better players.

  • Do not expect to win every game.
  • Queue times increase at the top of the ladder.
  • You will eventually stabilize.

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.

The system will try its best to match you with someone who has the same trophies AND a similar tower level.

True Fairness

This is why all true esports tournaments and competitive challenges utilize the 'Tournament Standard' ruleset.

Trust the math, ignore the conspiracy theories, and focus on improving your own gameplay.
