It's official: rock is dead. Or it could be, if paper and scissors have their way. The World Rock Paper Scissors Championship (WRPSC) will be making its first stop in Hong Kong this month, offering this leg's lucky winner a chance to win more than HK$71,000 at the Toronto finals. The best player from more than 500 contestants in the local competition will also receive HK$20,000 in food and cash vouchers to spend at the competition venue, Sha Tin New Town Plaza. The competition is split into a family division for teams of parents and children, a children's division for ages four to 10, and an open division for players aged 19 or above. The family and children's competitions will take place on October 18 and 31 while the open division will be held on October 18 and 26, and November 1. In town to launch the competition were WRPSC director Douglas Walker and 2004 WRPS champion Lee Rammage, who challenged fortune teller Paddy Ching Chung-kiu, Chinese wedding expert Chan Yuet-wah, and vice-chairman of the Hong Kong Mathematics Education Promotion Association, Cheng Li-ming. 'Every year, the carnival-like tournament will attract hundreds of RPS players dressed up to compete for the championship. Players' costumes are not for fun, but also a strategic move which prevents your opponents from studying your facial expression, [leading] to a bigger chance of winning games,' Walker said. He said he and his family use RPS to make everyday and life-changing decisions, such as which apartment to choose. Walker's father even used RPS as a dispute resolution mechanism in his will. The Hong Kong experts agree that RPS is a useful tool. Cheng said: 'RPS requires reflex actions and hand-eye co-ordination. It can improve calculation skills, probability concepts, logical thinking and reasoning ability.' Walker will also be training RPS ambassadors to serve as referees for the WRPSC Asia League, with workshops to be held during weekends and public holidays from October 18 to 31 at New Town Plaza. Shoppers who spend more than HK$200 at the mall can also join workshops which include free costumes and face-painting.
