The matchmaking algorithm is the unsung hero that determines exactly who you will face every time you press the 'Battle' button.
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
Most modern strategy games utilize a modified version of the Elo rating system, originally designed for professional chess.
When you go on a massive winning streak, your trophy count inflates, and the algorithm begins matching you against significantly better players.
- The algorithm does not care what deck you are playing.
- Accept the RNG.
- AI opponents ensure instant queue times for beginners.
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.
| Matchmaking Factor | Weight |
|---|
| Elo Rating | The system will always prioritize finding an opponent within a 50-trophy range |
| Account Strength | The system tries to match levels, but will abandon this check if the queue takes longer than 10 seconds |
True Fairness
This is why all true esports tournaments and competitive challenges utilize the 'Tournament Standard' ruleset.
The algorithm is blind; it only respects victory.
