Rules
The worked example on the home page follows the seeding and bye rule set out in the USA Badminton Tournament and Trials Regulations (rev. 1 Oct 2014, Reg. 1 and section 5) and Table Tennis Wales, Seedings and Draws: Ranking Events 2025/26 (sections 1 and 3), both read on 11 November 2026. The wording on our pages is our own. When the tools ship, every rule set they use will be listed here with its source and date.
Our own work
The pages, the worked example, the bracket drawing and the TournamentGrid mark are our own work.
