Ant and Dec roll out the red carpet for celebrity teams for the first time as Rylan, David Walliams, Jimmy Carr and Katherine Ryan take on the show for charity.

Jimmy Carr and Katherine Ryan continue their climb up the ladder, hoping to win big money for their chosen charities. Then, Geordie best friends, Helen and Kelly, think they've got what it takes to conquer the Limitless Ladder.

Husband-and-wife team Matt and Hannah take on the Limitless Money Ladder and play for a truly life-changing cash prize. Their daughter has her heart set on Disneyland, so the pressure's on to cash out before they crash out.

Contestants answer questions in a bid to win as much money as they can, with no limit to the amount of money they can have in the pot, but if they get the answer over by just one, they could lose thousands of already banked cash.

Ant and Dec host the quiz with a limitless money ladder and a never-ending jackpot. Married couple Crish and Karthy have a huge extended family and want to take them all on a huge holiday, so they're here to win a huge amount of money to pay for it - all they need to do is hold their nerve, find some exact answers, and make sure that they cash out before they crash out.

Ant and Dec are back with the final show of the second series - and a game that sees two plucky contestants play for over one million pounds. Husband and wife Nathan and Taylor are back to continue their journey up the ladder. Tracey-Jane and Troy, a mum and son duo from Liverpool believe that they might have what it takes to conquer the Limitless Ladder and change their lives forever.
