🎰 General Information

Book of Vikings is an online video slot developed by industry giant Pragmatic Play. Released in 2020, it takes players on an epic voyage through Norse mythology, with symbols depicting Viking warriors, longships, horned helmets, and the all-important Book. The game follows the classic “Book of…” mechanics made famous by Book of Ra, but adds a fresh Scandinavian twist and modern features.

The slot’s RTP of 96.5% is in line with industry averages, and the medium-high volatility ensures a balanced mix of smaller frequent wins and the potential for larger payouts during the free spins round. The game is fully certified and fair, using Pragmatic Play’s proprietary random number generator.

✨ Game Features

Symbols and Paytable

Book of Vikings uses a traditional 5×3 reel grid with 10 fixed paylines. The highest paying symbol is the Viking warrior, followed by the longship, the horned helmet, the Viking shield, and then the classic card suits (A, K, Q, J, 10). The Book itself acts as both the Wild and the Scatter – a powerful dual role. It can substitute for any other symbol (except the special expanding symbol during free spins) and also triggers the bonus feature.

Wild & Scatter

The Book symbol appears on all reels. As a Wild, it completes winning combinations; as a Scatter, landing three or more anywhere on the reels awards an instant cash payout and activates the free spins round.

Free Spins with Expanding Symbol

When you land 3 or more Book Scatters, you are awarded 10 free spins. Before the round begins, one regular paying symbol is randomly chosen as the special expanding symbol. During free spins, whenever that symbol appears on the reels, it expands to cover the entire reel and pays for all winning combinations – even if the symbols are not adjacent according to normal paylines. This can lead to massive payouts, especially if multiple reels are filled with the same high-value symbol.

Gamble Feature

After any win, you have the option to gamble your winnings. A simple card prediction game: guess the color (red/black) or the suit (hearts/diamonds/clubs/spades) of a face-down card. Correct color doubles the win, correct suit quadruples it. You can gamble up to 5 times in a row. Be cautious – one wrong guess and you lose the entire win.

Additional Mechanics

The slot includes an autoplay feature (up to 100 spins) and a turbo mode for faster gameplay. The user interface is clean and intuitive, with betting options ranging from 0.10 to 100 coins per spin, making it suitable for both casual players and high rollers.

🚀 How to Play

1. Set your bet: Use the +/- buttons to adjust the coin value. Each spin costs the coin value × 10 paylines. The total bet is displayed clearly.
2. Spin the reels: Click the large circular Spin button or use the spacebar on desktop. For continuous play, activate Autoplay and choose the number of spins (10, 25, 50, 75, or 100).
3. Understand winning combinations: Wins are paid for matching symbols on adjacent reels from left to right, starting from the leftmost reel. Only the highest win per payline is paid. The Book symbol pays as both Wild and Scatter – but if you land a line win with Wild substitution and also a Scatter win on the same spin, both are paid separately.
4. Activate free spins: Land three or more Book Scatters anywhere to trigger the bonus. You can also re-trigger free spins by landing three or more Books during the bonus, awarding an additional 10 spins. There is no limit to re-triggers.
5. Use the Gamble feature: After any win over 0.10, a gamble button appears. Click it to try to double or quadruple your win. You can choose to collect your winnings at any time.

For beginners, we recommend starting with small bets and using the free demo mode to get comfortable with the expanding symbol mechanics. The game is straightforward but offers depth in the bonus round.

💰 Bonuses and Free Spins

Triggering the Free Spins

The main bonus event in Book of Vikings is the free spins round, triggered by 3, 4, or 5 Book Scatters. The payout for the Scatter itself is 2x, 10x, or 50x your total bet respectively (based on the number of Books). Then you are awarded 10 free spins with a predetermined special expanding symbol.

The Expanding Symbol Mechanic

During free spins, the randomly chosen symbol (which can be any regular paying symbol) expands to fill the entire reel whenever it appears. This means that even if only one of that symbol lands on a reel, it will cover the whole reel and count as a win for all paylines that intersect that reel. For example, if the chosen symbol is the helmet and you land one helmet on reel 2, that reel becomes all helmets, and any payline that goes through reel 2 will have helmets. If you land multiple of the chosen symbol across several reels, they all expand, potentially covering the entire screen for a huge payout.

Retriggering

Landing three or more Book Scatters during free spins awards an additional 10 spins, and a new expanding symbol may be chosen (the same rules apply). Retriggers can keep the bonus going for a long time, leading to significant wins.

Gamble Feature Strategy

The gamble feature is optional and offers a chance to increase modest wins. However, due to the medium-high volatility, it is generally recommended to collect wins from the free spins round rather than gamble them. The gamble feature is better suited for small base game wins if you are feeling lucky.

Max Win Potential

The maximum win in Book of Vikings is capped at 5,000x your stake. This is achievable during the free spins round, especially if the expanding symbol is a high-paying Viking warrior and you cover multiple reels. While not as high as some ultra-high variance slots, 5,000x is respectable and aligns with the medium-high volatility.

📱 Mobile Version

Book of Vikings is fully optimized for mobile play. Pragmatic Play uses HTML5 technology, ensuring smooth performance on smartphones and tablets (iOS and Android). The game interface scales to fit smaller screens without sacrificing quality or usability. All features – including the gamble feature, autoplay, and free spins – are accessible via touch controls. The reels spin with fluid animations, and the graphics remain crisp. Mobile players can enjoy the same RTP and volatility as desktop users. We recommend playing in landscape mode for the best visual experience, but portrait mode is also supported.
