Session Name:

Math for Game Programmers: Ranking Systems: Elo, TrueSkill and Your Own


Many games require approximations of player skill based on past performance, from multiplayer matchmaking to single-player dynamic difficulty and contextual tutorials. This talk exposes the math behind standardized ranking systems like Elo and TrueSkill. Basic knowledge of statistics (normal distribution) is expected, although a big portion of the talk will be around practical considerations to design and improve your own ranking system.
