What to Expect from the Book of Winz Slot


Spinomenal, in collaboration with, has released a branded slot for the casino titled Book of Winz. The slot is a replica of the popular Spinomenal game Book of Rampage and plays out almost the same with one major exception. Instead of the Buffalo symbol, the Winz logo takes the central role as the Book and the highest-paying game symbol.

But since we are exclusively dealing with the Winz version of the slot, we must review it as a standalone title with a bit of reference to Book of Rampage. Either way, reviewing one game will automatically correlate with the other title. As a result, we won’t have to do a separate review of Book of Rampage, for the two games are absolutely identical save for the changed skin. 

How to Play Book of Winz


Book of Winz is a relatively simple video slot with 5 reels and 3 rows. Winning lines are limited to 10, and they cannot be modified. Bets start at a minimum of 0.10 coins and can manually increase up to 100 coins per spin. A thing to note about Book of Winz is that payouts are calculated per-line instead of paying on the total bet. Also, the game offers a maximum win potential of 5,000x the stake per line, which comes from none other than the Winz symbol.

The Book of Winz RTP varies according to region, but the best one available stands at 96.14%. The score implies that for every 100 coins wagered, the slot is expected to fetch 96.14 coins to the player in return. As for the variance, the game provider hasn’t disclosed any official info regarding it. But the way the game plays out, we expect it to follow the medium variance math model. So, players can expect frequent winnings in the game, but most wins are likely to be mid or below-average in size.

We found it yielding payouts quite frequently as we went through the slot. We didn’t have to wait too long to grab our hands on a win. But as is the case with medium variance slots, the win amount was often below the bet size. However, the equation changes once you step foot into the bonus game. The possibility of winning a big amount increases significantly with free spins, as it did in our case. One might get even luckier and hit the max prize cap during the bonus round. But, of course, that’s quite a rare feat, considering we played for a long time and didn’t even come near it. 

Theme, Design, and Sound

Book of Winz is almost identical to Book of Rampage, except for the Winz logo instead of buffalo. The background shows a nearby fence with a vast wild landscape in the far distance. The dry, rocky land illuminates the sunset’s gold hue, creating an aesthetically pleasant ambiance. Moreover, the imagery also suggests that nighttime is soon approaching us, and the wild creatures will come into action with it. 

It wouldn’t be incorrect to count it among the wild west-themed slots, but what gives Book of Winz a distinguished look is that it merges components from the Grand Canyon theme and also borrows elements from the ‘Book of’ slots. Hence, design-wise, it looks more like a hybrid. And as for the music, the background guitar score is catchy enough and again reminds of a typical wild west setting. 

Symbols and Payouts

In Book of Winz, payouts are computed on a per-line basis. For instance, if a symbol in a three-of-a-kind formation pays 25x at a bet of 2 coins per line (or a total bet of 20 coins across all pay lines), the winning payout would be 25 (credit) x 2 (bet per line) = 50 coins. With this equation in mind, let’s check out the slot’s paytable. 

Book of Winz Winning Pay lines of the slot game

Pay symbols are divided into three categories: low, mid, and high. Low-paying symbols include 10 to A card royals that pay 100x to 150x the bet per line for five matching ones. Among the mid-pays are the python, wolf, horse, and Winz logo, which offer 750x to 5000x the bet per line for landing a five-of-a-kind winning combination. Note that mid-symbols also pay when 2 identical ones land on a pay line. 

The Book or the Wild scatter are the most precious game symbols, for they not only pay 2x to 250x for 3 to 5 matching ones but also trigger 10 free spins. Also, as a wild symbol, the book substitutes for any other pay symbol. 

How to Win at Book of Winz

Features and Bonuses

Only one bonus feature is available in Book of Winz, but it holds massive potential to dish out incredible winnings. 

Free Spins

Hitting 3 or more wild scatters anywhere on the reels initiates 10 free spins, which can be retriggered. Cash value of scatter symbols payout separately. Before the feature starts, a wheel spins to choose a symbol randomly. The selected symbol could be any icon except the Wild Scatter symbol. Every time the chosen symbol lands during free spins, it expands to increase the number of slot pay lines. Note that the chosen symbol expands only when the expansion guarantees a win. Once expanded, the symbol pays out a winning line irrespective of whether these symbols are in consecutive order or not.

Buy Bonus 

Since the slot lacks multiple special features, triggering the only one present might be challenging. Hence, to make things easier, Spinomenal provides a bonus buy option. By paying 104x the stake, players can instantly step into the bonus game with a random expanding symbol. Note that the Buy Feature might not be available in some jurisdictions.

Our Final Words

Final Verdict

Players looking for a unique game experience won’t be much thrilled by Book of Winz. While the game brings visual elements from popular slot genres, it offers nothing new in terms of design and mechanics. But once you move past the initial impressions, the slot will start fascinating you more and more. The 10 active pay lines do not look enough, but in compact grid size, it works out rather well. The game also benefits from the medium variance math model, which frequently facilitates wins.

What we outrightly didn’t like about the slot is its user engagement appeal. Even though the numbers work well, it would have been even better had the slot provided some extra features to keep the playing sessions going. After a few spins, the gameplay wanes off quickly and starts relying heavily on its math to do some magic. But players only concerned with the math won’t find this much of an issue. 

The slot’s RTP and symbol payouts are neatly laid out among the positive aspects. But regarding the payout mechanism, it’s important to note that, unlike many other slots, Book of Winz offers prize money on a per-line scheme. While the per-line pay system has a reduced monetary size, players still stand a chance to win up to 50,000 coins, which is pretty good for a medium volatility slot. 

The USP of Book of Winz comes from’s and Spinomenal’s brand value. With such backing from the top platforms, the game’s user experience is smooth, and the added casino perks make this a dealbreaker. Moreover, the betting range is flexible and invites rollers of all types to participate in the game. And even as a standalone slot, the utter simplicity and frequent winning opportunities involved make Book of Winz a noteworthy title.
