What is the RTP and volatility of Book of Vikings?

Accepted Answer

The official RTP is 96.50% and the slot is classed as high volatility. Expect longer dry spells but bigger payout swings when the free spins hit.

Question 2

How do the free spins and expanding symbols work?

Accepted Answer

The Book symbol acts as both Wild and Scatter and landing three or more awards 10 free spins. Before the free spins start a single symbol is randomly chosen as the expanding symbol; when it appears on three or more reels during free spins it expands to cover the entire reel and pays for matches regardless of vertical position.

Question 3

How often do the free spins trigger?

Accepted Answer

Free spins trigger when three or more Book symbols land, awarding 10 free spins. In personal testing the feature does not always trigger quickly, so hit frequency can be relatively low.

Question 4

Are there other bonus features or a bonus buy option?

Accepted Answer

The review does not mention a bonus buy or additional bonus systems; the core mechanic is the Book triggering 10 free spins and the expanding symbol. There are no cascades, tumbling wins or multi layer bonus systems in this game.

Question 5

What is the maximum win and what does that mean in dollars?

Accepted Answer

The maximum theoretical win is 5,500x your stake. For example, at a $10 bet that equates to a $55,000 top payout.

Question 6

Can I try Book of Vikings for free and does it work well on mobile?

Accepted Answer

Yes, a full demo mode is available that replicates the real money experience so you can test the mechanics without risk. The game runs smoothly on desktop and mobile (iOS and Android) with fluid animations and a mobile friendly UI.
