Australian games developer Lightning Box has agreed a deal to launch a selection of games on the High 5 Casino free-to-play app.

The deal marks the first time that High 5 Games has added third party content to its social casino app, with Lightning Box' Chilli Gold slated to go live on December 7th.

The game is one of five that will be made available for social play exclusively on High 5 Casino, with Silver Pride – known as Silver Lion in Europe – to follow early in 2018.

Each title has already proved successful in the US land-based casino market, where they have been available through integrations with Incredible Technologies and Everi.

"We are delighted to be working with High 5 Games as we look to grow our business across all channels," Lightning Box founder and managing director Peter Causley said.

"High 5 were one of the first companies to bring gaming to social media and we are confident we can make their first third party deal a successful one with a product that has already proven popular with US players."

High 5 senior vice president of business development Jean Venneman added: "We look forward to distributing Lightning Box premium titles to millions of our High 5 slot enthusiasts who enjoy playing authentic content straight from the casino floor."
