Countdown Masters was the name of a series of Countdown mini-shows, broadcast weekly as part of the 'Channel 4 Daily' breakfast programme between 1989 and 1991. Each game consisted of 15 rounds and was split up into five parts so as to be broadcast over the course of a week (some matches would be shortened due to bank holidays or other events). Each daily segment consisted of a letters round, a numbers round and a conundrum, and would be broadcast more than once during the morning. Due to the short length of the shows, Dictionary Corner featured a lexicographer, but no guest.
