A lucky punter has won a £1.5m slots jackpot on his mobile phone.

The 50-year-old player scooped the cash – the largest ever mobile slot game prize – playing at the mobile site of online operators PartyCasino.

The man was killing time on his iPhone while out when he decided to play the five-reel Melon Madness jackpot slot, where minutes later he won a record £1,448,150.01.

The previous highest mobile slots win was an £866,000 prize claimed in July 2013.

PartyCasino director of games Golan Shaked said: Â"We are delighted one of our players has hit such an amazing jackpot and broken the world record for a slots jackpot won on a mobile phone.

Â"We are focusing a huge amount of time and energy on building the best mobile casino available and it is great to see our players enjoying and winning on our games.Â"
