The first episode of Ant & Dec’s new quiz show Limitless Win aired on Saturday January 8.

The new show sees contestants attempt to correctly answer questions and if successful, they’ll have the opportunity to win a cash prize.

Unlike any other quiz show, how much the contestants can win is an unknown figure because they will be playing for the world's first unlimited jackpot.

The first couple to take part were husband and wife Will and Kathryn, two NHS workers and they took home £500,000.

They began the game confidently and did well answering questions but after banking £100,000 they began to rapidly lose lives and got closer to ending their time on the show.

With very few lives left, they took the risk and decided to see another question.

After successfully answering it, their balance rose to more than £500,000.

The Doctor and Midwife were pleased to have continued their run on the show after they came very close to cashing out with just over £100,000.

They continued but shortly after their turn ended and they took home the cash.

Will and Kathryn currently rent their home but they are now thinking about buying a property with their prize money.
