We kindly ask all team leaders and coaches to review these hand signals with their team members before arriving at the competition venue. This will help participants understand referee instructions more easily, ensure smooth communication during matches, and minimize unnecessary misunderstandings or disputes.

Thank you for your cooperation, and we look forward to welcoming you to the 2026 WGM Contest.
