Ant & Dec’s Limitless Win

8.30pm, ITV

Here’s something that might just inject a bit of excitement back into Saturday night telly: the Geordie duo host a quizshow (their first new one in a decade) with a limitless cash prize. Yes, contestants can keep adding to the prize pot as they continue to answer questions correctly – but with more money available to win comes the increasing risk of losing it all. How far will they go? Expect jaws to drop (mostly Ant and Dec’s). Hollie Richardson

Celebrity Catchphrase

The Masked Singer

7pm, ITV

The berserk extravaganza continues. So far this season, we’ve been getting familiar with the cheerfully ridiculous new characters (Traffic Cone, Robo Bunny). But expect the guessing game to become a January national obsession as Davina McCall, Rita Ora, Mo Gilligan and Jonathan Ross take their places. Phil Harrison
