"Rules of the Game" is a 1983 single by UK pop group Bucks Fizz. The song was written by Warren Harry (under the name Warren Bacall), who had written their top 10 hit "When We Were Young" a few months earlier. It was produced by Brian Tench with co-production by Andy Hill. Released in November 1983, the single proved to be one of the group's least successful singles, peaking at No.57. Despite this, it remained on the Top 100 Chart for 10 weeks. The single was released in tandem with their first Greatest Hits album. The B-Side, "When We Were at War", a ballad, was written by the group themselves. At 6 minutes running length, it remains the longest song recorded by the group.
