About Mahjong X
Given the rise of prediction markets, this week arguably represents the most frenzied campaign since the historic PASPA decision in 2018. Buttressed by massive capital injection from substantial funding rounds, operators have spent handsomely on celebrity endorsements. Over the last week, ads featuring LeBron James, Sydney Sweeney, Marshawn Lynch and Jeremy Piven have showered the airwaves. Even Pete Sampras, who disappeared from the public spotlight for the better part of two decades, resurfaced in a US Open spot for Kalshi.
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.
How to play Mahjong X
Many players use a fixed cash-out target, such as 1.5x or 2x, and exit automatically every round. This removes emotion from the decision and keeps losses predictable.
The outcome of each round is determined by a provably fair system, which means every result can be independently verified. This transparency is part of why the format caught on so quickly.
As with any game, the house edge is real and the mathematics always favours the operator over time. Treat crash games as short bursts of entertainment rather than a strategy for steady income.
What is Mahjong X?
Bet365 noted the impact of the UK government’s near doubling of the remote gaming duty, which increased from 21% to 40% on 1 April this year.
Additionally, a new remote betting duty is set to come in from April 2027, which will raise the effective tax rate on all sports betting products except horse racing from 15% to 25%.
Several other operators have responded to the UK tax hikes by announcing shop closures.
