Book of Vikings is a Pragmatic Play video slot that sends players across dangerous northern seas in search of a legendary book. It runs on a 5x3 grid with 10 paylines and combines Norse mythology and medieval imagery with a Free Spins round built around an expanding symbol. This review covers how the game plays, what the numbers mean for your bankroll, and how to play safely.
Gameplay and Features
The base game follows the familiar book-style format. Five reels and three rows produce 10 fixed paylines, so wins come from matching symbols on those lines. The Viking longship, helmets and Scandinavian warrior imagery give the game a cohesive Norse and ocean look.
Free Spins Round
The main feature is the Free Spins round, where an expanding symbol is the key mechanic. Expanding symbols can cover entire reels and create several line wins on a single spin, which is why most of the game's potential is concentrated in this bonus. Check the in-game paytable for the exact trigger rules and symbol values.

Math Profile: RTP, Volatility and Max Win
The approximate RTP is 96.5%. This is a long-run theoretical average across a very large number of spins, not a prediction for any single session. Operators can run different RTP versions of the same game, so confirm the figure in the in-game info screen.
Volatility is medium, which suggests a balance between regular smaller returns and occasional larger ones. For bankroll planning, that means moderate swings: you can usually use modest stakes and still expect reasonable session length, but dry spells between features still happen.
The maximum win is 2,000x the stake. That is a sensible ceiling for a 10-line slot, though it is a rare outcome. Set your stake so that a long losing run will not exceed your budget, and treat any big hit as a bonus rather than an expectation.
Fairness, Licensing and Responsible Play
Online slots use a random number generator to determine every outcome. Independent testing laboratories such as eCOGRA, iTech Labs and BMM Testlabs test RNG output for statistical randomness, check that published RTP matches actual game maths, and review the integrity of the software. Their reports are one signal of a fair game environment.
Always play at an operator that holds a licence from a recognised regulator, such as the UKGC or MGA, and check the licence details in the casino footer with the regulator itself. Gambling is for adults aged 18 and over. Use deposit and time limits, never chase losses, and play only with money set aside for entertainment. If gambling stops being fun, organisations such as BeGambleAware offer free support.
