Williams Interactive has signed a multi-year agreement to provide its full portfolio of online casino slot games to UK bookmaker Ladbrokes.

Through integration with the Williams Interactive Remote Game Server, Ladbrokes.com players will have access to a library of authentic Vegas-style slot games, including Spartacus Gladiators of Rome, THE WIZARD OF OZ Ruby Slippers, Zeus III, and well known retail themes such as Crown Gems and Money Mad Martians.

Williams Interactive said that many of these games are already popular with players in Ladbrokes betting shops throughout the UK, provided by its UK-based sister company SG Gaming.

Richard Poole, head of product for Ladbrokes Digital, said: “We’re thrilled to provide the catalogue of Williams Interactive slot themes to our players later this year. The expanded access to themes already popular in our betting shops, including the fan-favourite Rainbow Riches, is an exciting opportunity to extend enjoyment of those themes for our players online and on their mobile devices.

“In addition, their wide array of one-of-a-kind game engines like Colossal Reels and Double Money Burst are already exciting online players across Europe, and will provide new and engaging casino options for our player community.”

Williams Interactive’s games are are expected to launch for mobile and desktop players on Ladbrokes.com by the middle of 2014.

“Expanding the reach of our deep catalogue of unique and innovative slot themes and game engines with one of the UK’s leading betting and gaming enterprises is another exciting step for Williams Interactive,” said Williams Interactive managing director Jordan Levin. “We believe that Ladbrokes players, who already enjoy our themes from our portfolio in Ladbrokes retail locations, will enjoy the omni-channel access this relationship provides them to our library of player-favourite slots at retail shops, from home, and on the go.”

The agreement is the latest step in Ladbrokes' revamp of its digital offering, with the operator recently launching a suite of casino games from Net Entertainment and Playtech.
