How to play Mystery Jack

In one of his Instagram stories, speaking directly to the camera, Pedro (a fictitious name for a “professional gambler”) shares a “unique opportunity”. He says that he is going to release a “super promotion for a premium group, which has higher odds”.

The normal price for access to the Telegram group would be BRL397 ($77.18) per month. But, exclusively on that day, he would release both groups together for “only BRL14.91 per month on the annual plan”. This group is the main product sold by Pedro, where he publishes sports predictions, tips on betting operators and higher-value betting odds.

The problem is that many of these recommendations involve companies that are not authorised to operate in Brazil. Some may be licensed in other countries, but that doesn’t allow them to operate legally in the Brazilian market.

What is Mystery Jack?

MGM Resorts International’s investment case is supported by Las Vegas, regional casinos, property assets and its 50% interest in BetMGM. Its own share price has been on a different journey to its online pureplay peers, having increased by 5% in a year, to $37.81 on 18 September.

“MGM offers a more diversified investment case, with BetMGM, regional gaming and Las Vegas operations reducing reliance on online sports betting alone,” says Beynon. Robinson makes the same point. “It is a Las Vegas and Macau property business with a betting JV attached, and that is precisely why it has held up.”

Entain sits somewhere between the two models. It has significant international scale and a valuable stake in BetMGM, but also more debt and greater exposure to UK taxation, as well as general regulatory turbulance across Europe.

The president of the Turkish Green Crescent Society, Associate Professor Mehmet Dinç, expanded on this point, highlighting the relationship between supply and demand in the fight against illegal betting. 

“In the fight against gambling, combating supply alone is not enough,” he said. “Combating demand alone is not enough; merely shutting down websites is not enough. This is an ecosystem: it starts with advertisements and continues through social media, sporting activities, influencers, games, mobile applications, payment systems, loans, bets, losses, debt and continued betting.”
