Countdown Masters Series 2
Countdown Masters Series 2 ran from April 1990 to March 1991, concurrently with Series 20 and 21 of Countdown. It was won by Andrew Fisher. From the third week, the scheduled broadcast time was moved again, to 9:19 am.
Episodes M54, M55 and M91 in this series were played over only four days instead of the usual five, as a result of games not being broadcast on certain days during the Christmas and Easter holiday seasons. The system of using the highest score of the series to determine the winner of the dictionaries was maintained, however, despite players in the four-day episodes being at a marked disadvantage for obtaining it: had Robert Coton (one such player) solved an additional numbers game and conundrum, and obtained a nine in the letters game, he would have won the series.
