What is Number King?

Calvinayre.com Editor-in-Chief, Bill Beatty – the Michael Kinsley of the gambling world. Bill just possesses that same rare gift of creating great writers. You won’t meet a more genuine guy that Bill, and I’m incredibly grateful for the opportunities to learn so much about the casino business, writing and how I see the world.

Lead reporter Rebecca Liggero Fontana for taking me under her wing. You won’t meet a more generous soul than Becky. She shares this unbridled passion for the casino and tech space, that is just contagious and I’m glad I got to experience that unabashed joy for the gambling industry.

I want to thank Derek Tonin, my editor who I would speak with every day I worked at Calvinayre.com. I’m grateful for the opportunity I have had to work with Derek. He’s an editor who doesn’t shy away from the blunt criticism and its inspiring being on the other end of the call. He’s a guy you would want in the foxhole right next to you, someone who isn’t afraid to give the blunt truth and also celebrate the wins with you.

About Number King

They connect four Instant Bonus tiers, Hold & Spin and two wheel-driven Bonus Spins modes, giving the game one consistent trigger throughout, while persistent multipliers make progression visible inside Bonus Spins and Super Bonus Spins. GO Ultra is the step up. Activating it removes standard Bonus Spins from the feature pool and introduces Super Duper Bonus Spins, with Coins concentrated on fewer reels and multipliers that grow in larger increments. The commercial hook sells itself on screen: Frank, the gnome gang over the fence, and a suburban garden turned battlefield. The game carries high volatility, with RTP configurations, exposure figures and other sensitive values retained in the internal fact sheet.

About Number King

Genius signed deals with both Polymarket and Kalshi in August, to provide real-time event data and league integrity services, as well as streaming services. Fellow data provider Sportradar also announced similar multi-year partnerships with both Kalshi and Polymarket in June. 

Initial reaction from investors was largely unfavourable. Genius shares plunged 13% on 18 Sept., falling 17% for the week. The data provider closed the session at $5.64 per share, well below the $6.19 price when it announced the Legend acquisition in February.

The launch of Prediction.com comes amid a strategic integration phase following Genius Sports’ acquisition of Legend.
