Championship of Champions
The Championship of Champions (often abbreviated CoC or C of C, or referred to in the shortened form Champion of Champions) is a televised knock-out tournament held every few years on the show between a selection of contestants who reached the final rounds of their series. Typically, only contestants who have appeared since the previous Championship of Champions are eligible to enter, however Darryl Francis was entered into Championship of Champions III rather than Championship of Champions II, and Jon Corby was permitted into Championship of Champions XIII rather than Championship of Champions XII as the line-up of XII was determined before he made his debut on the show.
During the early 2010s, the Championship of Champions tournament has been on a temporary, unofficial hiatus, seemingly because some members of the Countdown team believed it would increase the players' standard of gameplay beyond what the average viewer could appreciate. The 30th Birthday Championship, held at the start of 2013, was the only televised Countdown event longer than the series finals to take place during this period. Additionally, standalone special episodes were held between the two series champions of 2009 – Kirk Bevins and Chris Davies – and between the series champions of 2011 – Edward McCullagh and Graeme Cole; all four later entered the 30th Birthday Championship as well. The CoC hiatus ended with the airing of Championship of Champions XIV at the start of 2016.
The first eight CoC tourneys were each contested between eight people. From CoC IX onwards, they have been contested between 16, with the exception of CoC X, which was shortened to one week so as to conclude on New Year's Eve just before the turn of the 21st century. Each round is played in succession -- the eighth-finals (Championship of Champions IX onwards only), followed by the quarter-finals, then the semi-finals, and finally the grand final itself. The final for CoC I was a 9 round game. However, from then until the changeover to the (all-purpose) 15 round formats, CoC finals were 14 round games, in line with series grand finals.
