Players give up the standard mode to access a higher-variance version with steeper multiplier growth

The optional GO Ultra layer is where the release differentiates itself from a routine Hold & Spin title. 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 trade-off is deliberate. Players give up the standard mode to access a higher-variance version with steeper multiplier growth. The game carries high volatility, which positions GO Ultra as the risk-forward option inside an already volatile math model.

Holland Casino calls this Next Zone, and as Petra elaborates: “It’s an innovation we made a few years ago to see how we can develop a casino product because I think in the industry, we are very well known for what we have, but how do you innovate?”

Like most operators, slots make up the bulk of Holland Casino’s income, but it’s worth remembering that Holland Casino has a monopoly on table games, poker and bingo. “I would say those are also our hero products that make us attractive because in the Netherlands we are the only one offering land based live table games,” says Petra.

“Maybe they’re not so dominant in the results, but it is dominant in our identity. But figures-wise, slots are bigger than table games.”

Nolimit City has also leaned harder into optional purchase mechanics, a defining part of its recent output. Duck Hunters 2 offers an extensive collection of optional purchase features. These span direct bonus buys, targeted feature purchases, and a booster menu that resets starting conditions.

The Booster menu includes options designed to alter the starting conditions of a session. Players can guarantee scatter symbols, increase starting multipliers across the entire grid or activate enhanced bonus-hunting conditions. The strategic read is that Nolimit City is packaging multiple entry points into the same high-volatility engine. That gives players, and by extension operators, a variety of ways to engage a single title.
