GOSMA  – the Guild of Mind Sports Arbiters

An association of Independent, qualified referees for all mind sports


GOMSA is the first multi-sport refereeing and arbiting service for mind sport competitions. Its role is to train, raise standards, provide qualifications and professional development for its members, and enable the results and score of more mental challenges to be independently verified and accepted.
