About 40 King

Jackpots and free-to-play may be very different propositions, but Wilson judges both against the same unromantic measure: whether they produce value for the operator.

For free-to-play, that process can begin before the customer has committed money. “It’s about building muscle memory, providing achievable incentives to players and gamification,” Wilson explains. By lowering the barrier to participation, a free-to-play game can provide an accessible first interaction with an operator, while repeated play builds familiarity and creates a reason to return.

The format, however, cannot simply be copied and pasted from one market to the next. “We’ve found that the more localised the offering, the better,” Wilson says. “We’re talking about building anything from sumo wrestling to Love Island, as well as the headline sports. Ice cage fighting has been a popular one in a certain market for us.”

Premier League clubs are prohibited from any form of gambling front-of-shirt sponsor, after a voluntary ban came in from the start of the 2026-27 campaign.

But Entain found 11 of the current 20 Premier League clubs still hold sponsorship or advertising arrangements with operators that don’t hold a UK licence, up from the government’s estimate of eight.

The deals include sleeve sponsorships, stadium branding and training kits.
