Virachkul represented the United States internationally in darts tournaments. He competed at the first
Embassy World Darts Championship in 1978, losing narrowly by 7–8 in the semi-final to eventual champion,
Leighton Rees. He won third place in a play-off by defeating
Stefan Lord. Virachakul reached the quarter-finals on three other occasions: in 1981 (losing to
Eric Bristow), 1982 (losing to
Bobby George) and 1984 (losing to
Dave Whitcombe). Despite his respectable record, it was nevertheless a surprise when he defeated the defending World Champion,
Keith Deller, in the first round of the
1984 World Championship. Deller had his revenge in the first round the following year. The 1985 championship was Virachkul's last appearance in the final stages. Despite competing in the first eight World Championships, he never again qualified after the tournament moved to the
Lakeside Country Club in 1986. Virachkul competed in the third
WDF World Cup darts tournament in 1979 and won the singles title. In 1980 he reached the semi-finals of the
Winmau World Masters. He also won the 1978 Windy City Open, the 1982 North American Open and the 1983 Dallas Open. Nicky Virachkul was inducted into the National Darts Hall of Fame in 1996. == Death ==
