Equilibrium is a free, browser-based poker theory trainer designed to help no-limit hold'em players study GTO (game-theory optimal) decisions. Play infinite randomly generated preflop and postflop spots, get instant scoring against solver-aligned ranges, and track your progress with an Elo-style rating system.
Preflop opening ranges by position, calling and 3-betting versus opens, defending the big blind, squeeze frequencies in multiway pots, c-bet sizing on different board textures, double barreling on turns, river value betting and bluffing thresholds, pot odds and equity calculations, and how to think about ranges instead of single hands.
Every hand is generated on the fly. The app deals random hole cards and simulates a realistic action history, then asks you to choose between fold, call, raise, check, or bet at the appropriate sizing. Your action is scored against solver-aligned EV calculations using Monte Carlo equity simulation. Optimal decisions earn rating points; mistakes are queued for review.
