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

Many players believe that matchmaking is intentionally rigged against them, constantly forcing them to fight 'hard counters' after a win streak.

The Elo System Adapted

Your trophy count is a numerical representation of your skill; win a match, and you take trophies from the loser.

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.
• If you face a hard counter, it is pure statistical variance.
• In the lower arenas, the system often includes 'bots'.

Level-Based Matchmaking

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.

The Esports Standard

By artificially capping all card levels to a specific number, the algorithm can rely purely on the Elo rating.

When levels are equalized, the matchmaking system shines, ensuring that the better player almost always wins.
