Common questions

How does Lichess calculate chess puzzle ratings?

Lichess puzzles utilize the Glicko-2 rating system. Both the player and the puzzle have a rating and rating deviation. When you solve a puzzle correctly, your puzzle rating rises while the puzzle's difficulty rating adjusts dynamically based on community success rates.

What is Tournament Performance Rating (TPR)?

TPR represents the hypothetical rating level a player performed at during a specific tournament or match series. It is calculated by determining the rating at which your expected score against the given opponents matches your actual score.

What is the difference between Elo and Glicko-2?

While traditional Elo uses a single number, Glicko-2 introduces Rating Deviation (RD) and Volatility. RD measures the uncertainty of a rating: active players have a low RD (~45-60), meaning ratings change gradually, while inactive players have a high RD causing larger rating swings.
