Red Tiger slots were relatively new to the industry a few years ago but surged in popularity, prompting NetEnt to buy the supplier – before NetEnt was then bought out by Evolution.
The newly launched games include Bounty Raid, 777 Strike and Reel Keeper, soon to be added to by Cash Vault, Piggy Riches Megaways and Gonzo's Quest Megaways (already live on BetRivers.com in Pennsylvania).
Richard Schwartz, recently promoted CEO of RSI, said: "We are excited to partner with Evolution to bring these top-quality and much-loved Red Tiger casino games to our players in Michigan.
"RSI was the first to debut the Red Tiger games in the US where they are already some of the top-performing games in Pennsylvania. We are thrilled to now launch Red Tiger in Michigan, where we are sure these games will become fan favorites for our loyal players there as well."
Jeff Millar, Commercial Director, North America for Evolution, said: "We're very proud to be partnering with RSI, a highly acclaimed US operator, to debut our very successful Red Tiger games in Michigan.
"This collaboration with RSI will allow us to deliver these popular games to other markets in the US in an accelerated fashion, and will help strengthen our position as a top provider in the online casino category."
Millar will exclusively feature in the September/October edition of Gambling Insider magazine, discussing exactly this topic – Evolution's expansion in the US and Canada.
