Quickspin takes on a genuinely huge theme with an equally huge set of numbers in Hammer of Vulcan, a release that also marked the studio's first-ever bonus buy option, making it a fitting title for that feature's debut in the Quickspin catalogue. Nearly every aspect of the game has been super-sized, especially the win potential, and the studio leaves players with a fitting parting question: are you worthy of such a treasure?
This isn't Spock's home world — Quickspin has gone with the Roman mythological Vulcan instead, god of fire, traditionally depicted with volcanoes looming over his forge as he crafts divine items for the pantheon. The studio has done a genuinely good job of conveying his scale over the player: the view sits down at roughly the level of his sandals, looking up at the towering figure, producing a tilted perspective on the 6x4 grid that takes a few spins to get used to, all perched atop a giant anvil. The setting is the bowels of Mt Etna in Sicily, and a fittingly heavy atmosphere settles in quickly, helped along by a creeping, plodding soundtrack that suits the molten, forge-bound theme well.
The grid runs on a win-all-ways structure across 4,096 ways, formed whenever matching symbols land across the reels. The paytable opens with 10-A card royals before moving into tongs, shields, helmets, swords, chalices and gold golem symbols, with six-of-a-kind premiums paying out between 4.5x and 12x the stake. Standard wilds share the same value as the gold golem symbol and substitute for other paying icons across the grid.
Hammer of Vulcan carries a 95.8% RTP, a fair figure that sits close to, if slightly below, the broader slots average. Over a large number of spins, that translates to a theoretical return of roughly £95.80 for every £100 wagered.
Rated high volatility at 5 out of 5, this is a slot built for genuinely bumpy sessions — expect the math model to swing between rewarding and punishing spells much like the mythological deities it's themed around. Stakes run from 0.10 up to 100 per spin, playable on any device.
The advertised max win sits at a huge 20,347x the stake, one of the more striking numbers in Quickspin's catalogue and a genuine showcase for what the studio's math team can do when given room to push volatility to its limit.
Hammer of Vulcan pairs a genuinely imposing visual presentation with a headline win figure that lives up to the theme's grandeur. As Quickspin's first bonus buy release, it also holds a bit of historical significance within the studio's catalogue. Well worth a spin in the free demo at johnessyslots to get a feel for that tilted forge-eye view before playing for real money.
