HBO Developing ‘Advantage Player’ Casino Drama Based on Gina Fiore’s Life, Starring Riley Keough

HBO has put into development Advantage Player, a new drama series starring and executive produced by Riley Keough. Written by Daisy Jones & The Six co-creator Will Graham, the show is inspired by real-life professional gambler Gina Fiore and her upcoming memoir tracing her career as a high-stakes card counter.

Fiore — who began her career as an advantage player by teaching herself card-counting while working as a blackjack dealer at an unnamed casino on the Las Vegas Strip — spent 24 years legally beating casinos using skill-based technique rather than luck.

Fiore’s upcoming memoir, Advantage Player: Blackjack, Backrooms, and Beginnings, will be published Oct. 27, 2026 by Gillian Flynn Books, an imprint of Zando/Penguin Random House.

In a blub she wrote for Fiore’s book, Keough gushed that Fiore “has lived a life that seems too extraordinary to be true.” She called Fiore’s journey “as gripping as any screenplay because every impossible twist actually happened.”

“Riley listened to a podcast I did for The Ringer network in 2020,” Fiore told Casino.org. “She liked my story, we spoke, and she’s championed the idea ever since.”

According to Deadline, Keough’s version of Fiore will be “a brilliant misfit (who) discovers the secret to beating casinos at their own game.”

Taking ‘Advantage’

Advantage play refers to methods such as card-counting, hole-carding, and other legal strategies that give skilled players a mathematical edge over the house.

Fiore — who will also executive-produce the HBO series — rose through this secretive world, eventually building and leading teams that extracted millions from casinos while constantly adapting to increased surveillance, rule changes, and the risk of being identified and banned.

“I’m grateful we got a deal,” Fiore said. “I know how hard that is. Just to be able get in the room to pitch a show is difficult. Will Graham and Riley Keough’s reputations and talents made that happen.

“I couldn’t ask to work with better people,” She concluded.

With Keough attached to lead and production moving forward at HBO, Advantage Player promises a rare, insider look into the high-stakes world of professional gambling from a woman who beat the house at its own game.
