Introduction to Book of Wild Review
The Book of Wild online slot can be played as a free slot, and on the surface it is pretty straightforward to get to grips with the gameplay. But 1spin4win slots shake things up a little with the use of the Wild symbol, which has the image of (you guessed it) a book. This symbol acts as a wildcard, meaning it will substitute for any and all symbols to help you match a row. If you get three, four or five of these symbols in the same spin, you will be awarded with bonus spins. You win 10, 15 or 20 free spins depending on the number of symbols, and a multiplier depending on which random symbol you receive before starting the bonus round.
You can play Book of Wild as a free slot in demo mode above, and we recommend you do this to get a feel for the game as well as reading our slot review before you decide to play for real money at an online casino.
Graphics & Soundtrack
Book of Wild slot has smooth gameplay with vibrant graphics. The soundtrack is atmospheric but is played at a subtle volume. The sound effects are a little louder and stand out more, but they are not invasive or distracting.

Book of Wild RTP and Variance
The RTP (return to player) of Book of Wild online slot is 97.4%, which is good compared to some other slot games. Volatility for this online slot is high, with a top win of 5000x, which, while alluring, does mean you will have to be patient waiting for those wins due to the high volatility of the game.
How to Play Book of Wild
Here’s how to get started playing Book of Wild online slot as part of our slot review:
- Once the game has loaded, it’s always a good idea to go to the menu first. The button is located in the bottom left corner of the screen with three horizontal lines. Click the info button within this menu on the left-hand side to read the game rules, points per winline and winning row combinations. Combinations must be from left to right in order to win.
- There are a number of different symbols, each with their own points value depending on how many you match. This varies quite a bit and at first glance can be a little confusing. It’s worth spending a minute getting familiar with the prize structure.
- Going back briefly to the main menu, this is where you can toggle turbo spin on and off. This speeds up the gameplay significantly and makes the whole experience more exciting.
- Select your bet amount on the bottom of the main screen. You have 18 stake options in increasing increments ranging from 10 to 1000.
- Autoplay is easily activated, as the button is located next to the Start button on the main screen. With both turbo spin and Autoplay enabled, the game is fast-moving and fun and keeps you engaged.
- Set your win/loss limits and your budget for the session, and hit either Autoplay or Start to play manually. Remember to enjoy Book of Wild responsibly, and when the fun stops, stop.
Min & Max Bets + Top Wins
You can choose a stake between 10 and 1000. There are 10 paylines, with winning combinations from left to right. The lower-value symbols are 10, J, Q, K and A, while the higher-paying symbols are animals and birds such as an eagle or wolf.
You can view the paytable in the information section under the menu. The highest possible win in the main game is x5000 for matching five wolf symbols.
Book of Wild Bonus Features
The bonus spins round is triggered when three or more book symbols appear anywhere on the screen (they don’t have to make a combination). When this round is activated, you will also be awarded another symbol at random. This will expand during the free spins and act as a multiplier for your winnings and varies depending on the symbol. You win 10, 15 and 20 free spins for three, four or five book symbols respectively.
Our Verdict
This is a fun online slot with vivid graphics and quick to get started. The turbo and autoplay features combined make for fast-paced gameplay. There are limited bonus features, which is a little disappointing, and the high volatility means you may have to wait a while for wins. That said, the RTP is on the higher side, and overall it’s an engaging, easy to play slot.

FAQs
What are the RTP, Volatility and Max Win of Book of Wild?
Book of Wild has a good RTP of 97.4% but with high volatility, so you will have to be patient and wait for wins. There is a maximum single bet win of x5000 your stake if you match five wolf symbols, although if you’re especially lucky on the bonus spins and expanding symbol, there is the potential for higher wins.
What Are the Bonus Rounds?
There is one bonus round of free spins when you land three or more book symbols in a single spin. You’ll be awarded 10 free spins for three books, 15 spins for four books and 20 spins for five books. A randomised symbol acts as a multiplier in this round.
What are the multipliers?
Multipliers are only available on the bonus spins, which is disappointing. It does, however, have the unexpected effect of making the bonus round more exciting, as the exclusivity makes the free spins more rewarding. At the start of the round you are assigned a symbol at random which expands and multiplies your wins.
