Vulkan Vegas slots

Slots fill most of the Vulkan Vegas lobby – thousands of titles from the big studios and plenty of smaller ones. Here is how the slot section is organised, which games are worth a look and how to choose by numbers rather than by theme.

How the slot lobby is organised

The slot lobby opens on a popularity ranking, which is useful but mostly reflects what other players are spinning this week. More practical are the filters:

• New – the latest releases, usually from Pragmatic Play, Hacksaw and BGaming, which publish new games every week.
• Classic – three-reel fruit machines and simple five-reel games with few features.
• Jackpots – games with a fixed or progressive jackpot on top of the normal pay table.
• Bonus buy – slots where you can pay a fixed price to go straight to the bonus round.
• Providers – the quickest way to find a specific studio's catalogue.

Every tile opens an information panel with the game's rules. Most slots also have a demo button that lets you spin with play money, which is the best way to see whether you like a game before spending anything.

Popular slots at Vulkan Vegas

Good to know: Many studios release the same slot in several RTP versions, and the casino chooses which one to offer. The "default" figures above are the providers' standard versions. Always open the game's info screen to see the RTP that applies at Vulkan Vegas in your country.

RTP and volatility – the two numbers that matter

RTP (return to player) is the share of all stakes a slot pays back over millions of spins. A 96% slot keeps €4 of every €100 wagered on average. It says nothing about your next session, but over time a 96.5% slot costs you less than a 94% one.

Volatility describes how the winnings are distributed. Low-volatility slots pay often but little; high-volatility slots can go a hundred spins without much and then pay a large win. Neither is better – it depends on your budget and what you enjoy.

Our article on the welcome package shows how volatility affects the chance of completing a wagering requirement.

Jackpot slots

Jackpot slots add a prize pool on top of the normal pay table. Fixed jackpots pay a set multiple of your stake. Progressive jackpots grow with every bet until someone hits them. The price is usually a lower base-game RTP, because part of every stake feeds the jackpot. They are fine for the occasional dream spin, but they are a poor choice for wagering a bonus.

Bonus buy slots

Bonus buy lets you pay a fixed price – often 100 times your stake – to trigger the free spins round straight away. It speeds the game up a lot, and with it the speed at which a budget disappears. Bonus buys are normally excluded from bonus play, so use them only with your own money and a clear limit.

Slots and bonus wagering

Slots usually count 100% towards wagering requirements, which is why most bonuses are designed around them. Three things to watch:

1. Excluded games. Some high-RTP and high-volatility slots are on an excluded list in the bonus terms. Spins on them do not count, and playing them with bonus money can void the bonus.
2. Maximum bet. While a bonus is active, the maximum stake is €5 per spin.
3. Feature buys. Buying a bonus round is not allowed while wagering.

Playing slots on your phone

Almost every slot in the lobby runs in the mobile browser and in the Android app. Modern slots are built for portrait screens first, so they often look better on a phone than on a laptop. Older titles may open in landscape only. Spins use the same RTP on every device.
