How to play Book Of Immortals

There is also a natural product opportunity. Splash Tech has traditionally been weighted towards sports within free-to-play, while RubyPlay brings a substantial casino ecosystem. For Wilson, the agreement creates a chance for Splash Tech to bring its distinctive engagement thinking into the RubyPlay world, planting a seed for future products that combine Splash Tech’s free-to-play and jackpot expertise with RubyPlay’s content ecosystem, market knowledge and distribution reach.

For RubyPlay, Splash Tech supplies a way to move beyond games and towards a broader content-and-engagement proposition. For Splash Tech, RubyPlay supplies the reach to take already proven products further. And for operators, the value is practical: a flexible engagement layer that can sit across casino, sportsbook and third-party content, reduce operational complexity and create more reasons for players to keep coming back.

Want to continue the conversation? Adam Wilson will be joining the RubyPlay team at SBC Summit in Lisbon (STAND B411) between September 29 and October 1, where operators can learn more about Splash Tech’s free2play games, jackpot engine and approach to lasting player engagement.

About Book Of Immortals

For so long, CalvinAyre.com has been a beacon in the poker reporting landscape but as the outgoing incumbent of this position of privilege, I haven’t been at the centre of this role for so long as to claim anywhere near all the credit.  

A huge thanks for his outstanding reporting on this site should go to Lee Davy, who for many years, brought poker to life on Calvin Ayre. I personally owe a huge debt of gratitude to Lee for the efforts he made in not only making me feel so well prepared to take up the mantle when he moved on to pastures new, but in establishing the Calvin Ayre brand so well for so many years within the poker world.

Ours is a niche industry, but it is a wonderful and welcoming one, and Calvin Ayre has been a huge part of the poker industry in my time, too. The name has opened doors, helped me speak to some of the biggest and best poker players from around the globe.  

What is Book Of Immortals?

While Polymarket pulled off a coup with the signings of James, Eli Manning and Derek Jeter, a Novig ad featuring Sweeney arguably received as much fanfare. Sweeney, an Emmy Award-nominated actress known for her role in HBO’s Euphoria series, stars in the spot titled “Just Sports.” As of Friday afternoon, the Novig post on social media platform X received at least nine million views.

Throughout the ad, Novig throws shade on its rivals for offering niche markets on events such as the timeframe for when traders believe that Venezuelan President Nicolás Maduro will be removed from office. Unlike operators such as Kalshi and Polymarket, Novig has opted to limit its offerings to purely sports. “No betting on wars, or deaths…or politics,” Sweeney mused.

During the 2025-26 NBA season, Kalshi made waves by granting an equity stake to two-time league MVP Giannis Antetokounmpo. According to the Wall Street Journal, Sweeney’s representatives approached Novig to express interest as a potential investor. Eventually, the company granted her an undisclosed amount in equity. The increased role of celebrity endorsements in the space is a trend that will likely receive closer observation in the coming months.
