He won two games unbeaten in Series 56, but had to retire for personal reasons without losing a game. The producers allowed him to continue his run in Series 57 where by chance he faced seven-time winner Mikey Lear. The game was close throughout, but May avoided a crucial conundrum by spotting DUSTIER in the last letters round. May went on to win three more games before losing to Steve Baines who would by coincidence also go on to win 7 games and lose the final 8th one.
In January 2010, May attended his first unofficial Countdown tournament, COLIN 2010 where he managed an impressive 5th place.
May is set to re-appear on the show in Series 79.
