The TV presenting duo could be set to release the likes of computer games, books, and puzzles with the popular ITV programme's name and branding.

According to the Daily Mirror newspaper, the 'I'm A Celebrity' co-hosts' production company Mitre Studios Ltd lodged an application with the Intellectual Property Office, and it has now been passed, giving them legal protection for the next 10 years.

But they will not be creating any 'Limitless Win' gambling applications.

A spokesman for the duo said: "'Ant and Dec’s Limitless Win' will not be creating gambling machines, phone betting apps, lottery scratch cards, bingo games or any gambling applications based on the programme."

'Ant and Dec's Limitless Win' - in which contestants answer questions correctly to climb an endless money ladder, or answer incorrectly and lose everything - will return for a second series on Saturday (07.01.23).

Last February, the show was commissioned for a second series while the first season was still on air.

Ant McPartlin said at the time: "We are thrilled that 'Limitless Win' has been a hit with the viewers and is coming back for more.

"We're beyond excited to be able do it all over again and we can't wait to find new contestants to play the first TV show with a limitless jackpot!"

Declan Donnelly added: "We're already preparing ourselves for another series of nail-biting drama, jeopardy and tension as we present more questions you can't help but Google!

"We're expecting more, and higher, dizzying climbs up the Limitless money ladder. We can't wait."

The first two episodes of the show saw big wins, with NHS workers Will and Kathryn taking away £500,000 and father and son Tony and Zee closely following with £250,000.

Katie Rawcliffe, ITV Head of Entertainment Commissioning, said: "'Ant Dec's Limitless Win' has quickly become an audience favourite, with families up and down the country playing along from home- from searching their kitchen cupboards to identify the length of a Pringles tube to Googling the width of Michael Jordan's handspan.

"It was a no-brainer to have the high stakes game show return."
