An Introduction to Book of Rampage
In the online casino world, we see a lot of different concepts being used in slots. However, Spinomenal likes to pick the lesser-used themes quite often. In this case, they’ve went with something atypical for the Book of Rampage online slot.

This game is based around the North American desert wilderness, which is full of interesting animals and dangerous places.
We really like seeing different themes presented in awesome ways. That’s exactly what we get with this title. Lots of animals from the area are shown on the reels in a tremendous amount of detail. On top of that, a great desert background is used with mesas and other landmarks. It really captures the feel in a very serious way. Additionally, even the card rank symbols are styled in a way that’s perfect for the concept of this title.
The gameplay is handled in a fun way that makes sense as well. They went with a high hit-rate here. When that’s paired with the balanced pay table and features, you end up with a lot smaller swings than you typically see on average. It’s a really fun style of play that is a good fit for the majority of players. However, if you’re looking for huge swings and a high volatility, you won’t find that here.
Betting and Layout
The format for this title is set up to facilitate all of the action. As such, Spinomenal went with something straightforward and easy to get used to. Here’s what you can expect in this game:
- You won’t have any big surprises with the format here. It’s a straightforward game with five vertical reels and three horizontal rows.
- Players will always be using 10 paylines in this game. The number of lines cannot be adjusted in any way.
- All of the paylines go from left to right. Additionally, winning combinations must start with the leftmost reel.
- The bet size selector shows you the wager per line. You multiply that by 10 to get your total bet size. However, that total size is also shown directly below the selector.
- Along those lines, you can wager €0.01 per line at a minimum for a total minimum bet size of €0.10 per spin.
- Likewise, the largest line wager is €10 apiece, which leads to a €100 maximum bet size per turn.
As we mentioned up above, the volatility is well below average. We would place it somewhere on the lower end of the medium-low range. This means that your swings will be fairly low on average, and your hit-rate will tend to be higher than most games.
We also want to point out how bets are described in this title. They’re all based on multiples of your bet size per line. For example, if you’re wagering €10 total, which is €1 per line, and pick up a 50x win, then your payout is worth €50. To convert these values to multiples of the total bet size, simply divide by 10.
Gameplay and Features
The feature set of the Book of Rampage online slot is really easy to get used to. However, it still provides a fair amount of action. It also helps with getting a lot of smaller and medium-sized wins, which keeps the volatility so low. We’ll show you what you need to be familiar with before you get started in this game in the following.

Wild Symbols and Payouts
The book itself from the title of the game is the wild symbol in this slot. It’s a large book with a golden buffalo’s head on the cover. This wild also appears on every one of the five reels, and it gives some very strong line-based payouts:
- Five of a Kind – 5,000x
- Four of a Kind – 1,000x
- Three of a Kind – 100x
- Two of a Kind – 10x
If you get a winning combination of wilds, the game will check to see if they can be used to give a better payout as a substitution instead. For example, if you have three wilds followed by a horse symbol, there are two potential payouts. Three wilds pays 100x, but four horses gets you 400x. To make sure you get the best payout available, each line is evaluated independently for the best individual prize. In this example, you’d be given the four of a kind win on that particular payline.
As a result, note also that these scatters can substitute for multiple symbols on multiple lines. Overall, it really just means you’re getting the best wins available from these wild symbols.
Scatter Symbol Prizes
In the Book of Rampage video slot, the books are both wilds and scatters. Additionally, they give scattered wins that are calculated separately from any line-based payouts. The following scatter prizes are available, based on multiples of the entire wager:
- Five of a Kind – 250x
- Four of a Kind – 25x
- Three of a Kind– 2x
You can get both regular and scatter wins for the same set of wilds. For example, if you picked up five wilds on a payline, you’d be given a 5,000x prize for the line bet win and 250x (multiplied by the total bet size) for the scatter payout.

Free Spins With Special Expanding Symbols
Three or more of the scattered wild book symbols anywhere on the game board will also trigger free spins. You’re given 10 free spins to begin with. However, you can also re-trigger them to add 10 more by getting three or more scatters during the round itself. No limit is placed on the maximum number of free spins you can get in this way.
At the beginning of the feature, a non-book symbol will be chosen at random on a spinning wheel. This wheel is the special expanding symbol for the feature.
During the free spins, after each regular spin, the regular wins are counted. From there, all expanding symbols will grow to cover their entire reels, and they will pay out once again for any possible wins. However, this is made more valuable because they do not have to be located on adjacent reels. This makes it much easier to get a lot of wins at once.
How to Win at Book of Rampage
With the volatility being a fair bit below-average here, you’ll have a pretty easy time with the swings in most cases. Additionally, the hit-rate is higher as well, which also helps. This puts players in a position where a betting adjustment can be viable.
While it’s completely optional, you can increase your bet size somewhat by about 33 percent or so. This will give better wins in the absolute sense. However, your relative volatility and swings will still be pretty reasonable. Again, this is a totally optional adjustment, but it’s something to consider because of how low the volatility is in this title.
Payout Structure for Book of Rampage
All of the top symbols in this game pay for just two of a kind. That’s one of the factors that keeps the hit-rate high and the volatility fairly low. For the buffalo or horse symbols, you can get 5,000x or 2,000x for five of a kind, respectively. Additionally, both the wolf and rattlesnake symbols in five of a kind combinations pay out 750x. All four of these animal symbols (in addition to the wild line-based wins) start paying at just two of a kind on a line.

That leaves the card rank symbol wins, which come in two tiers. The red A and orange K pay out 150x for five. However, you can also score 100x for five of the yellow Q, green J or blue 10 symbols.
