SpinOnline — Table Tennis Community & Tournament Platform

• Manual management: Running tournaments and practice sessions by hand is laborious and error-prone in pairing, fee collection, and result aggregation.
• Fragmented information: Tournament info and schedules are scattered across organizers, making them hard to find.
• No skill metric: There was no common rating to evaluate players' skill levels across events.
• Weak community: Little mechanism to connect organizers with players and encourage participation.

Centralize table tennis tournaments and practice sessions online, visualize skill through a rating system, and build a community connecting organizers with players.

• Centralized online management: Tournament info, practice sessions, match results, entry-fee points, and schedules in one system.
• Rating system: A proprietary S/O rating with SS–D ranks to visualize skill, plus world rankings.
