About Sinful 7s

Entain has issued a stark warning in a letter addressed to Prime Minister Andy Burnham about the potential impact of a proposed increase to the Machine Games Duty (MGD). 

Ahead of the government’s Autumn Budget in October, Entain CEO Stella David cautioned that doubling the current MGD rate to 40% could result in widespread closures of betting shops and significant job losses, while potentially reducing tax revenues for the government.

A potential MGD rise was first reported in the The Financial Times, as Chancellor John Healey is allegedly looking to raise the tax, on the recommendation of the Social Market Foundation, which proposed the increase in a recent report.

Rather than building each slot from scratch, the studio appears to lean on recognizable frameworks it can dress in new themes. 3 Aztec Spells reads as another application of that model, not a departure from it.

Aztec is one of the most heavily worked themes in the world of online gambling, and Spinomenal is far from alone in returning to it. The setting offers the gold, temple, and idol imagery that has long anchored adventure-styled reel design.

What stands out is how often Spinomenal itself revisits the territory. A single provider maintaining multiple Aztec-flavored slots suggests the theme performs reliably enough across operator networks to justify repeated entries.
