Book of Vikings at 5gringos Casino: what you need to know
A Pragmatic Play Norse-themed slot with 5 reels and 10 paylines. Trigger free spins with the Book symbol, then watch one chosen symbol expand to fill entire reels. High volatility with 96.50% RTP.
What kind of game is Book of Vikings?
How the grid and theme work together. Book of Vikings takes you across five reels and three rows, where a Viking chieftain, shield-maiden and golden artefacts clash on ten fixed paylines. The Norse theme runs through every symbol, from horned helmets to drinking horns, all set on a high-volatility game released in 2021. The main mechanic is the expanding symbol: during free spins, one randomly chosen symbol fills a reel each spin, creating wins anywhere it appears once a combination forms. This feature transforms the bonus round into something quite different from the base game.
Who this game rewards most. High volatility means wins arrive less often but land much bigger when they do. Book of Vikings suits players who can handle longer dry spells and have a bankroll to match, especially those chasing substantial payouts rather than steady small wins. The game runs from NZ$0.10 to NZ$250 per spin, so casual players can start small, yet the expanding symbol feature during free spins creates the potential for large hits. If you prefer frequent small wins, this slot's rhythm will feel different from what you're used to.
Where the expanding symbol truly matters. The free spins round reshapes the game entirely. You trigger it with three or more Book symbols anywhere on the reels, which awards ten free spins. Before each spin, one random symbol expands to fill an entire reel vertically, paying anywhere once a win lands. If three or more Books land during the bonus, you gain another ten spins, and this can retrigger endlessly. The base game has none of this expansion; the free spins round is where the slot's true volatility and biggest payouts come alive.

Your free spins moment and how it changes the reels
The expanding symbol that unlocks bigger payouts. Three or more Book symbols anywhere on the reels award ten free spins. One random symbol expands vertically to fill an entire reel during the bonus round, then pays anywhere when a win forms. Three or more Book symbols during free spins retrigger ten more spins, with no limit to how many times this can happen.
How matching symbols line up for a payout. Five reels and three rows hold ten fixed paylines that run left to right from the leftmost reel. Matching symbols on a payline create a win, and only the highest payout per line counts. When you land wins on multiple paylines in one spin, all payouts add together.

How much does the free spins purchase cost?

What nobody can know before you spin
Bonus timing stays hidden. The Book symbol arrives unpredictably. No spin count or betting pattern determines when the free spins trigger lands. Every session is its own chance.
Today's result varies from the odds. Your session result is random. The 96.50% RTP describes long-term returns across many players over time, not what happens in yours today or tomorrow.
Maximum win arrives very rarely. Book of Vikings pays up to NZ$1,375,000 at the maximum stake, yet such wins are extraordinarily rare. The ceiling exists; reaching it does not.

Keep your play in check while you spin
Before you play: decide your spend. Decide on a budget you can afford to lose entirely before your first spin. Treat every stake as money gone once you've placed it.
Plan your exit point. Plan in advance when you'll walk away, whether you're ahead or behind. A win doesn't mean you should keep playing longer.
Lock in your limits. Use 5gringos Casino's deposit limits and loss limits on your account to enforce the boundaries you've set. These tools block spending beyond your cap.
Pause or step away. Book of Vikings is entertainment. If it stops being fun, or if you feel you're chasing losses, take a break or use self-exclusion.
