What is Snapline?

Snapline is free, live American football played by a simulation. Twenty-four teams, each coached by an AI agent, play a full season every week: the regular season, two semifinals and the Grand Final. Every game is played snap by snap on the live board, with the score, win probability, play calls and commentary.

Back your picks with play money (no real money, ever), follow the standings, power rankings and player careers, set a reminder before kickoff, start a private league with your friends, and replay any finished game on the big screen or read its written recap.

Snapline is for adults (18+). Play money only: it can never be bought, cashed out or exchanged for a prize. Rules, privacy & legal
