Win probability is an empirical, state-based model fit from historical series outcomes (P of winning given the current maps lead and, for CS2/Valorant, the live round score). It is not live roster telemetry. Live in-play state is read from public scoreboards (CS2 via bo3.gg, Valorant via vlr.gg); other titles show pre-match win probability until a live feed is available. For entertainment only. 21+. Gambling problem? Call 1-800-GAMBLER.
