What is Cool Diamonds II?

Holland Casino has a responsible gambling board, which includes scientists, experts with lived experience and their own RG executives. They meet with the board every few months to talk over current processes, and the board challenges the operator’s ideas and implementations, pushing them to do better.

“They challenge us both from an academic side and a more practical side. We try to develop our rules as we go along but you have to prove every single day that you’re doing all that you need to do on responsible gaming,” Petra notes.

The Netherlands online gambling market has been the subject of many column inches and much speculation thanks to regulation that has been largely described as heavy-handed and perhaps a little short-sighted – even by the country’s own regulator.

Remote casino, betting, and bingo activity was the standout channel, generating £8.3 billion in GGY, a 6.9% year-on-year increase and accounting for approximately 63% of the non-lottery industry yield.

Online casino stood at £5.7 billion for the 12-month period, of which £4.8 billion was derived from slots. Remote betting came in at £2.4 billion, led by football (£1.2 billion) and horse racing (£769.3 million). Remote bingo GGY was at £147.8 million.

Quarterly data from January to March 2026 reinforced this trend, with online verticals generating £2.2 billion, and remote casino alone accounting for 68.3% (£1.5 billion) of that total.

That modular approach is the reason the release stands out in a crowded segment. Rather than funneling players into one static bonus, Play’n GO gives Triple Beasts of Fortune multiple entry points that can stack. This changes how volatility and payout potential accumulate across a session.

The design is organized around color-coded Crystal Scatters, each tied to a distinct feature path. Every color is paired with a matching skull display and feature path: green for Upgrade, blue for Expand and red for Multiplier, and each feature awards seven spins as standard.

Each path alters a different part of the math model. Upgrade Free Spins turns Bison symbols into Thunder Bison that pay twice the standard value, while Expand Free Spins opens the grid to five reels by six rows and 7,776 payways. The third path introduces multiplier wilds to the middle reels.
