Golden Grimoire

About Golden Grimoire

Durango opened in December 2023 following an impressive $780 million development. The property completed its first $120 million expansion in December 2025, and work on the latest project began in January 2026.

The second expansion is expected to take about 18 months and remains on schedule to open during the second half of 2027, according to Red Rock Resorts president Scott Kreeger.

The latest project will add more than 275,000 square feet to the north side of the resort. The expanded casino floor will include 400 additional slot machines, while new entertainment options will include a 36-lane bowling facility and luxury movie theaters.

What is Golden Grimoire?

Greek mythology remains one of the most durable and repeatedly mined themes in slot development. Zeus, Olympus and storm imagery give studios instant visual shorthand and reliable player recognition, which is precisely why developers keep returning to it. REEVO going back to that well signals a preference for proven commercial territory over riskier concepts, at least in this part of its roadmap.

This is a mainstream release designed to fit widely rather than to stand out

For operators, the appeal of a title like this is straightforward. You get a recognizable theme, a medium-volatility math model and a multi-feature package that slots cleanly into a mixed lobby. For REEVO, each release like Thunder Walker broadens the content it can offer partners and reinforces its identity as a volume provider working within established formats.

How to play Golden Grimoire

Pragmatic Play and studio partner Reel Kingdom are extending their Big Bass franchise with Big Bass Splash Halloween 1000. It’s a Halloween-themed release scheduled for October 12, 2026.

The more telling point for slots readers isn’t the game itself. It’s what the game represents: the fourth Halloween-branded entry in a single series, which shows just how aggressively Pragmatic Play iterates on its most recognizable slot IP.

Rather than building a new title from the ground up, the release uses Big Bass Splash 1000 as its base. The franchise’s signature Money symbol collection mechanic stays intact while a seasonal skin gets swapped in.
