8 Out of 10 Cats Does Countdown is a British comedy panel show hosted by Jimmy Carr. It is a crossover of 8 Out of 10 Cats and game show Countdown. The show follows the format of Countdown, but with hosts and contestants from 8 Out of 10 Cats, and an emphasis on the humour seen on 8 Out of 10 Cats. All episodes are approximately 45 minutes long, and usually featured team captains Sean Lock and Jon Richardson; after Lock's death in 2021 his team has been led by a rotating series of guest captains, until 2025 when he was replaced by Rob Beckett, while Richardson continues to be a regular captain.

Lock and Richardson never appeared together in this series.
This series is composed of unaired episodes as a result of the COVID-19 pandemic. The first two episodes were recorded in late 2019 to accommodate Rachel Riley's maternity leave, made obvious by the fact she still appears 8-months pregnant in these episodes; the third episode was originally filmed in early 2019 as references were made to Richard Ayoade's role in the "recent" film '; and the fourth and fifth episodes were Best Bits specials that were originally assembled in 2018. The Christmas Special was also filmed in 2019, prior to Riley's pregnancy.
The last series broadcast prior to Sean Lock's death in 2021. The first three episodes were shot in 2019.
The first four episodes were filmed in March 2025. The fifth episode was filmed in 2023 and was shown first internationally, shortly before its UK broadcast; details of the episode, including scoring, were leaked online in January 2025. The first and second 'Best Bits' specials were compilations of highlights from episodes filmed in 2023, with the third comprising highlights of episodes filmed in 2022.
From this series, Rob Beckett became a permanent team captain, with Judi Love making semi-regular appearances as a panellist. This series also saw a change to the format in an additional panellist being given to the team losing late in the game.
At least two episodes were recorded in September 2025, with a further four filmed in November and another two in December. Four of these were broadcast as part of series 29, with the rest later in 2026. Guests for the remaining episodes in that filming bloc were confirmed to include Katherine Ryan, Harriet Kemsley, Richard Ayoade, Morgana Robinson, and Nick Mohammed.
Separately, an episode purported to have been filmed as part of the thirteenth production run in late 2019 - comprising a lineup of Sean Lock and Joe Wilkinson, Jon Richardson and Katherine Ryan, and Tom Binns as Ivan Brackenbury in Dictionary Corner - has never been shown. It is unknown if a UK airdate was ever scheduled, however BBC UKTV in Australia did intend to broadcast the episode in January 2022. In 2023, Binns was convicted for possession of child sex abuse imagery. A segment from the episode - not featuring Binns - was released on Channel 4's official YouTube channel, as part of a compilation of highlights from the show, in April 2025.
