# GoatLab > GoatLab is a family of free sports career simulator games that run in any web browser with no download and no sign-up. The core loop: spin a slot-machine reel of real professional athletes, lock one player per attribute slot to assemble your own custom player, then simulate their entire career, season by season, awards, injuries, championships, and a final Hall of Fame verdict. Every game has a daily challenge where the whole world gets the same spin seed and competes on one leaderboard.
