EFM League is a free online football management game developed by YAGAMES, where players take charge of clubs in a persistent football world. Designed for fans who want to build and manage a team over time, the league brings together real managers competing for promotion, titles and player value. Club management goes beyond matchday: managers shape their squads and line-ups, set tactics, oversee training and finances, and develop youth players.

A central feature is the live transfer market, where managers can scout players, track market values, place bids and negotiate deals. The game also includes league tables, match results, cup competition, promotion and relegation across nine tiers, and options for stadium expansion. Player form and fitness help inform team selections, while individual player profiles add identity to the league.

EFM League is available to play in a web browser, with iOS and Android apps also listed. Managers can connect with the community through Discord and the forum to discuss tactics, transfers and the evolving competition.
