The Asian-themed, five-reel, 1,296-ways slot uses the supplier's patented Reelfecta super reel to give players 16 chances to win on the middle reel, as well as a Mega Spin where all 16 positions are Wild.
The game has been a major hit in U.S. land-based casinos, including The Cosmopolitan of Las Vegas and Treasure Island, and will now be available online to Mr Green players for an exclusive two-week period before going to general release.
Peter Causley, Lightning Box managing director and co-founder, said, "Astro Cat is a really great game that has enjoyed phenomenal success in land-based casinos, particularly in the U.S.
"We're very excited about taking it online in Europe, firstly through Mr Green and then more broadly across the whole market in the coming months. I'm sure players will love the design of the game, as well as our innovative Reelfecta super reel."
Andrew Crosby, Head of Casino at Mr Green, said, "Astro Cat is an awesome game, which is why we wanted to bring it to our players first. We are always looking for new and exciting titles to boost our portfolio, and this is a great addition."
