Taskmaster Norway: Christmas special

Each Challenge pits numerous cast members from past seasons of reality shows against each other, dividing them into two separate teams according to different criteria, such as gender, which show they first appeared on, whether or not they're veterans or rookies on the show, etc. The two teams compete in numerous missions in order to win prizes and advance in the overall game.

I gathered 1,000 people to fight for $5,000,000, the LARGEST cash prize in TV history! We're also giving away a private island, Lamborghinis, and millions more in cash throughout the competition! Go watch to see the greatest show ever made!

Celebrities compete in a singing competition with one major twist: each singer is shrouded from head to toe in an elaborate costume, complete with full face mask to conceal his or her identity. One singer will be eliminated each week, ultimately revealing his or her true identity.

It's the "Nailed It!" holiday special you've been waiting for, with missing ingredients, impossible asks and desserts that look delightfully sad.

The show where everything's made up and the points don't matter. Not a talk show, not a sitcom, not a game show, Whose Line Is It Anyway? is a completely unique concept to network television. Four talented actors perform completely unrehearsed skits and games in front of a studio audience. Host Drew Carey sets the scene, with contributions from the audience, but the actors rely completely on their quick wit and improvisational skills. It's genuinely improvised, so anything can happen - and often does.

"Come on down!" The Price Is Right features a wide variety of games and contests with the same basic challenge: Guess the prices of everyday (or not-quite-everyday) retail items.

Each week, 20 contestants compete in a series of challenges in an attempt to win £10,000. These challenges are based in large pools of water or mud and generally involve large assault courses that participants must cross.

A relentlessly fast-paced baking competition that challenges brilliant bakers to create sweet treats that look and taste amazing – all against the clock. Who will race to the finish and win $10,000?

This game show sees contestants solve word puzzles, similar to those used in Hangman, to win cash and prizes determined by spinning a giant carnival wheel.

Britain's best amateur bakers compete in the iconic white tent - all united in their aim to prove their baking skills and impress judges Paul Hollywood and Prue Leith.
