About Great Rhino

Holland Casino was one of the first operators out of the gate when the newly-minted market opened in 2021, and while they don’t have the position they occupied in those early days, the company’s online offering is healthy. When they launched online, Petra says “we were very well known for – and are very well known for – responsible gaming.

“That was the reason why we joined [online as well as land-based]. But we were a full brick-and-mortar company so it took us some time to prepare for that market. In the beginning, the market share was of course higher because you only had 10 operators and we had a very well-known brand name, but now the market is much bigger and you have operators more specialised in sports betting and things like that. We have dropped down a bit.”

The Netherlands has a government that may be a little heavy handed, a regulator that knows this, and a monopolistic operator that’s trying to do its best for the customer. The industry is an active participant in trying to erradicate the growing illegal market. This week, state-lottery operator Nederlandse Loterij took action against the offshore operator behind the brand Skyhills, ordering them to cease serving Dutch players.

What is Great Rhino?

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 Great Rhino

Notably for highly engaging verticals light online slots, if players are receiving a smaller-than-expected RTP (return to player), or bonuses have been restricted, they could again transition to an illegal offering where there are no such restrictions.

As has been flagged in previous reports, Regulus highlighted that the top 1% of active customers accounts for almost 50% of black market revenue across Europe. This follows a similar trend across licensed gambling as the report highlights “online gambling is a consumer discretionary expenditure item. This means a large proportion of expenditure is concentrated into a relatively small number of players.”

In its market-specific breakdown, the report noted a “rapid reduction in channelling” in the UK, following the increased use of affordability checks.
