What is Only Diamonds?

Air travel is booming, but Las Vegas isn’t seeing the same lift, as tourism numbers remain turbulent.

Through July, the Las Vegas Convention & Visitors Authority (LVCVA) reported that visitor volume has rebounded only 0.5%. 2026 followed a difficult 2025, where visitation crashed 7.5%.

Far fewer travelers are arriving in the casino town by air this year. Harry Reid International Airport reported 30.2 million passengers through July—a 6.9% drop from the same period in 2025—with international traffic down nearly 9%.

Seasonal releases are an important part of the studio’s content strategy. 1spin4win regularly builds games inspired by international celebrations, among them Christmas, New Year, St. Valentine’s Day, St. Patrick’s Day, Easter, Halloween, and Oktoberfest.

For operators, that predictability is the point. The approach provides ready-made content for holiday campaigns and year-round themed promotions.

Welcome to Octoberfest isn’t a standalone idea. It’s the newest addition to a defined sub-series, joining Beersburg Fest Hold and Win and Lucky Fest Hold and Win in the studio’s line of Oktoberfest-inspired slots.

When asked which operator will be willing to take the risk and ultimately win Japan’s next “licence lottery”, Klebanow contends that it depends on how restrictive – or attainable – the regulations and requirements imposed by the government will be.

“If policymakers once again impose onerous policies that limit a property’s profit potential, then most developers will not take the risk of investing upwards of $10 billion in an IR development,” says Klebanow.

One exception, he notes, could be the Seminole Tribe of Florida and their proposed Hard Rock Resort Casino in Tomakomai, Hokkaido.
