Rarestone Gaming Casinos

Rarestone Gaming is an Australian based software development studio for the online casino industry. Playtech, a leading front runner in games development acquired the company in 2018, adding to it’s huge portfolio of development and production solutions, enhancing their presence in the marketplace.

About

The company was co-founded by Anton Tjioe, a long-standing games designer for IGT for over ten years, previous to this he worked for GLI test labs.

James Stewart is another highly acclaimed team member who is now the head of games development for Rarestone Games. James spent nearly 20 years working for Playtech, previous to this he spent time with WMS, building a team who developed over 24 slots for the Australian market.

Games

Playtech had shown a keen interest in the company quite soon after launch, taking note of the innovative design and unique features in their games including the Hold and Respin Feature. Six games have so far been released sharing the game feature with each game offering a second bonus mechanic, each unique to the previous. Players are intrigued by the suspense of what the new titles offer next from the previous, which in turn keeps players interested in their games.

Since they came on board with Playtech, the first release was Fire Blaze: Sky Queen, the game offers the unique features and to date, is said to be one of the most popular Playtech titles.

The Fire Blaze Jackpot series of games including Blue Wizard sits nicely by the side of Playtech’s Age of Gods series but with unique, new features to look forward to. The Fire Blaze series also offers four jackpots through the Hold and Respin propriety; these are the Mini, Minor, Major and Grand jackpots.

Since its launch, the company have developed over 13 games for Playtech, each offering unique features and bonus mechanics. The multi-talented team is intent of doing everything right and so far have ticked all the boxes for Playtech and players alike.
