Understanding Basketball Game Score

What is Game Score?

Game Score is a basketball performance metric created by John Hollinger as a simplified version of Player Efficiency Rating (PER). It evaluates individual player performance in a single game by weighing positive contributions against negative actions.

Why Use Game Score?

  • Single number representation of overall performance
  • Easy comparison between players across different games
  • Accounts for both positive and negative contributions
  • Used by NBA analysts and sports media

Game Score Formula

GS = P + 0.4×FG - 0.7×FGA - 0.4×(FTA-FT) + 0.7×OR + 0.3×DR + S + 0.7×A + 0.7×B - 0.4×PF - T
