Diamond Doggies

What is Diamond Doggies?

An Australian casino player is taking Royal Caribbean to court, arguing that the company banned him from sailing with its services and from playing at its casinos over his ability to count cards. After previously winning a legal battle against Star Casino, Mark Timothy Grant is now moving to confront the cruise line. 

Grant argues that he has booked five Royal Caribbean cruises that were valued at a total of AUD 22,000. He booked the cruises with money he won playing at the Royal Caribbean’s ships’ casinos. 

However, before he could even board the first cruise, Grant was told that he would not be able to proceed onboard. Grant had his son and partner along with him. The company only then went to inform Grant that he had been placed on a “no sail” list, effectively a ban, because of “breaking the house rules” in the casino.

The lesson is simple: gambling still attracts capital when the money is visible. It is less attractive when the payoff lies far in the distance.

The biggest new uncertainty in US sports betting is prediction markets. The American Gaming Association estimates that Americans will legally wager $29.5 billion in betting handle through US regulated commercial sportsbooks during the 2026 NFL season, broadly unchanged from the $29.4 billion handle recorded in 2025. These figures refer to the amount wagered, not sportsbook revenue.

Robinson calls prediction markets “the main event”. His argument is not simply that US customers are moving from sportsbooks to prediction markets. The more important point is that sportsbooks no longer have the relatively protected market that was once assumed.

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.
