THE GAME

About 21–0

21–0: Badminton World Tour is a free browser game about drafting historical player-year cards and taking them into simulated competition. The name comes from badminton's 21-point scoring format.

Game modes

Choose singles or doubles cards from 1990–2026, test your draft in a knockout tournament, or keep your entry through a World Tour season. Build a national or mixed-country legends roster in the Thomas, Uber, and Sudirman Cup modes.

Results unfold rally by rally with commentary. Follow the full match, speed it up, or skip to a result with the complete rally history still available. In season play, fatigue, injuries, tournament points, and Finals qualification make the schedule part of the challenge.

Access and advertising

The game is single-player against simulated opponents. It runs in a browser, requires no player account, and has no subscriptions or in-game purchases. Informational pages may display Google AdSense ads; the gameplay screen has no web display ads. Advertising choices and the optional Android test-ad preview are explained in the privacy policy. Ratings are informed by historical results and adjusted for the game's cross-era format.

An independent simulation

21–0 is an unofficial project. It is not affiliated with, sponsored by, or endorsed by the Badminton World Federation, any tournament organiser, team, or player. Names identify the historical players and competitions represented in the game; they do not imply a partnership. Ratings, calendar arrangements, and outcomes are part of the simulation.
