GTO stands for "Game Theory Optimal"—a mathematically balanced poker strategy that cannot be exploited. While no human plays perfect GTO, understanding it helps you make better decisions and identify when opponents deviate from optimal play.
You earn points for matching the GTO-correct action, with bonus points for accuracy on close decisions. Mixed strategy spots (where multiple actions are correct at different frequencies) reward you based on how often GTO takes your chosen action.
