How to play Rat King

That positioning has clear trade-offs. High-volume, template-driven studios rarely lead the market on standout mechanics. What they do offer is a steady pipeline for operators and a familiar, low-friction experience for players across a large library.

3 Aztec Spells fits neatly into that pattern. It is best read not as a landmark launch but as evidence of a content engine designed to keep Spinomenal’s numbered, theme-clustered families growing.

On the strength of this release and the surrounding catalog, the provider appears committed to that model for the foreseeable future. Iteration and volume over reinvention, for now.

With such a significant rise in tax, you would forgive the company for cutting wherever possible, but Petra says they have made it work by maximising efficiency, restructuring, and maintaining their offering so the customer doesn’t notice that anything has changed.

“We feel that people are always interested in gambling and that we are the party who should offer that in a safe way. [Holland Casino] has been careful to maintain that, but of course our costs rose very quickly, so we restructured at our head office. We have also been looking at innovations in offerings, which we are currently also testing, including a further development of the Next Zone. We’ve also introduced the double zero in roulette, which we didn’t have previously in the Netherlands,” the CEO says.

“Obviously, in the gaming industry we don’t have a price tag on our product where you can just change the RTP (return-to-player) and your problem is solved, it doesn’t work like that. Especially not if you take responsible gaming seriously.”

What is Rat King?

The design decision matters more than the garden-war premise. Coins can award an Instant Bonus, open Hold & Spin, or launch one of the wheel-driven Bonus Spins modes. That gives the whole feature set one consistent trigger.

That consolidation is the news hook. Rather than spreading activation across scatters, dedicated bonus symbols, and separate triggers, Play’n GO has made one symbol responsible for every route into a feature.

Everything runs through Coins. The Coin connects the four Instant Bonus tiers, Hold & Spin, and the two wheel-driven Bonus Spins modes, giving a busy feature set a single point of entry.
