Ant & Dec's Limitless Win | Series 4 Preview (ITV1)

The ground-breaking format, created by Hello Dolly and co-developed by Hello Dolly and Mitre Studios, is once again giving contestants the chance to play for the world’s first unlimited jackpot.

The unique never-ending money ladder - which has had a makeover and is now bigger than ever - sees contestants take on a series of questions where every answer is a number.

From ‘How many segments are in a chocolate orange?’ and ‘How long is a man’s size 10 foot in centimetres?’ to ‘How many fingers and thumbs can be seen on The Mona Lisa?’ hosts Ant and Dec guide contestants as they attempt to climb the Limitless ladder. Correct answers will bank them cash.

But if they go over, even by one, they’ll crash out and leave with nothing. With a vast array of fiendish questions, including new music-based questions, viewers will be shouting at the telly as they join in this latest appointment-to-view series.

And with contestants getting higher up the ladder than ever before, huge cash prizes are on the line. Plus there’s a lifeline that sees contestants able to turn to Ant and Dec for help. How will the hosts fare when the tables are turned?

Ant & Dec's Limitless Win returns Saturday 4th January on ITV1.
