How to play Queen Of Rio

In 2009, despite having relinquished any active role in the online gambling industry years earlier, I launched CalvinAyre.com due to my dissatisfaction with the news sites that then dominated discussion of the gaming sector. I found their coverage too deferential to the established giants of the day and too oblivious of the changes I saw looming on the horizon.

I didn’t invent online gambling, but I saw its potential early enough to help shape the industry in ways that allowed it to emerge from the shadows into the mainstream.

For those who came looking for archived CalvinAyre.com gambling articles, they live on [here]. For those looking to learn more about the endless possibilities of BSV – including how it will impact the gambling industry – I encourage you to visit [CoinGeek.com] and join me on my next great adventure.

Betfred’s retail business still heavily depends on fixed-odds betting terminals (FOBTs) and in-shop gambling. Despite the maximum stake limit being cut to £2 in 2019, FOBTs account for roughly half of Betfred’s shop profits. Done emphasised that without these machines, retail betting wass “impossible”.

According to Done, such a tax rise would lead Betfred to close 495 of its shops within a year, resulting in the loss of 2,575 jobs and roughly £67 million in foregone tax revenue for the Exchequer.

Betfred has already shuttered 132 outlets this year, following last year’s RGD increase.

The two related businesses are associated with entrepreneur Nic Brereton and had only recently started operating under their own licences. BresBet was licensed in February 2025, while Bet St George received its licence in December and launched in March this year.

At launch six months ago, Brereton told iGB that Bet St George would use the experience he gained applying advanced data models in the medical sector to improve the customer experience in betting.

“Sometimes what data tells you is uncomfortable because it’s challenging the norm,” he said at the time. “For me [it’s about] where we can make some marginal differences by using player data and challenging the perspectives of what the industry thinks should and does happen.”
