What is ELO?

The ELO rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess, or in our case, Lorcana tournaments. It was originally developed by Arpad Elo for chess competitions.

Each player starts with a base rating (1000), and this rating changes after each match based on the outcome and the relative skill difference between players.

How Does It Work?

Examples

Key Points

• • Ratings are relative - they only matter in comparison to other players
• • Beating stronger opponents gives more points than beating weaker ones
• • Your rating stabilizes over time as you play more games
• • Draws result in no ELO change for both players
• • The system is self-correcting - ratings tend toward your true skill level
