On what date did Teamfight Tactics release for Windows and macOS?

Teamfight Tactics released for Windows and macOS on June 26, 2019.

Riot Games launched Teamfight Tactics as a League of Legends game mode during the auto-battler boom sparked by Dota Auto Chess. Rather than releasing it as a separate boxed product, Riot integrated TFT into the League client, making it available to existing PC players on Windows and macOS.

The date is often confused with TFT’s mobile launch. Android and iOS versions arrived on March 19, 2020, nearly nine months after the desktop release. That distinction matters because June 26, 2019 refers specifically to the Windows and macOS launch.

TFT uses League champions, items, traits, and visual themes, but its battles are largely automated after players position units and make strategic choices. The game became a major permanent part of Riot’s ecosystem rather than remaining a short-lived experimental mode.
