The operator has no international locations. Well, it’s a state monopoly, after all. Holland Casino was also one of the first operators to launch online when the market legalised in 2021, with Petra de Ruiter joining the company as CEO the following year.
Petra’s journey to the role started in a hotel management school where she learned the ropes of hospitality, followed by a job at Transavia Airlines, a subsidiary of renowned Dutch operator KLM. This led to 24 years in the aviation industry, in a host of different roles: sales, marketing, operations – all aspects of the business that would later become useful in the casino industry.

About Mystery Heist
I would be lying if I said it’s going to be easy to accept this transition and to refocus my efforts elsewhere. However, I am eternally grateful for having been given this excellent opportunity and have enjoyed every aspect of being involved in the Calvin Ayre organization. What is coming next may still not be defined, but that’s what is going to make the next chapter exciting; it can bring essentially anything and everything. What I know, regardless of what happens next, is that I will continue to be who I am and will continue to provide the same level of professionalism and integrity that have brought me this far, and which are paramount for everyone involved with Calvin Ayre. I thank everyone at the organization for their undeniable commitment to excellence and thank all of our supporters and readers for allowing us to share with them our experiences and knowledge.
If anyone wants to reach out to me, I can always be found on LinkedIn.

Moshupa/Manyana MP Karabo Gare opposed the lower age limit during parliamentary debate. “When a person is still 18, he or she cannot make informed decisions, hence they end up being addicted to the game,” he said.
Botswana Congress Party MP Kenny Kapinga also argued that parliament should retain the current minimum age of 21, saying younger adults remained vulnerable to early exposure to gambling.
In January, Acting Gambling Authority CEO Moruntshi Kemorwale said reported problem gambling had declined from 5% in 2020 to 3.4% in 2025. It was a change he attributed in part to the regulator’s National Responsible Gambling Programme and nationwide education and outreach.
