The ‘Book of’ slot mechanic has already proven to be quite reliable, and once again it does live up to its name, paying a fortune of more than120 ETHto some lucky gambler, who was spinning on the Book of Cats slot from BGAMING on March, 10. Playing with abet of 0,05 ETHper spin, this fortunate punter made it to Free Spins, which resulted in an amazing2,582x win.
We’ve said it before perhaps, but if there is a nuclear holocaust the survivors will be cockroaches and book slots. Book of Cats is, despite the title, not filled to the brim with cuddly furballs. The theme is very much inspired by ancient Egypt, like so many Book of clones before, but now you have an additional reel that can expand to complement your base game wins.
The math model creates an interesting dilemma here. You can win bigger than usual because of the high value symbols, but the low RTP will drain your bankroll more than most other book slots out there. Overall, this is a decent enough addition to the book saga, and it comes with few twists that some players might find attractive.
Instead of the regular 5 reel setup, you will play with 6 reels here. However, the reel positions on the 6th reel are blocked except the middle position. Whenever you land a winning combo involving the symbol on the 6th reel, the reel positions open up and reveal the same symbol. This increases your payout, and the feature is called the Winline Expanding feature.
You can also choose to gamble any win here, and this is done via the double or nothing feature. You will guess the color of a face-down card, and if you guess correctly you will double your winnings. If you guess wrong however, you lose everything.
The golden book symbol is both the wild and a scatter, which is common in book slots. It will therefore step in for all regular symbols to help you create winning combos, and it also pays 40x for 5 on a payline. When you land at least 3 book scatters anywhere in sight, you trigger the free spins bonus round.
This is a standard book slot bonus round. You will get 10 free spins, and the symbol that lands in the open reel 6 position becomes the chosen expanding symbol. The expanding symbol doesn’t need to land adjacent to create winning combos, and you can retrigger the feature indefinitely by landing 3 new scatters.
In any book slot the expanding symbol you get will basically make or break your bonus round. You can see how we fared in the highlights video below, and the bonus round starts around 1 minute into the video. We have some decent base game wins before that however, and you’ll get a good feel for the gameplay by checking it out.
Well, what can we say. Yet another Book of Ra clone, and centered around holy Egyptian cats this time. The good news here is the high symbol value, where the top symbol pays 750x for 5 on a payline. If you get this as the chosen expanding symbol you can win up to 7,500x your stake by filling the screen. The max win cap is set at 10,000x in total from the bonus round, which is twice as much as most book slots.
The only really original contribution to the overcrowded book slot series is the Winline Expanding feature. This means that your base game wins will be complemented at times, but you pay a price in the long run because of the unusually low RTP of only 94 %. So there you have it. You get twice the potential here with a more rounded volatility than most book slots, but it will bleed out significantly more of your bankroll over time.
Pros
Cons
If you likebook slots, there are more than 150 of them in our catalog at the time of writing. New clones crop up every month or so, and we’ll recommend some of the best ones for you below.
Book of Dead- is the book slot that never gets old. It’s not only the most popular book slot in the series, it’s also one of the most popular games ever created. You will benefit from expanding symbols in the bonus round, and wins up to 5,000x can be landed.
Legacy of Dead- is another highly popular book slot from Play’n Go, and it comes with up to 9 expanding symbols in the bonus round. This adds to the already exciting concept, and you can win up to 5,000x your stake in this highly volatile title also.
Ali Baba’s Luck- takes the book slot concept even further, and allows for expanding symbols also in the base game. All winning symbols become highlighted, and will expand on the next spin. In the bonus round however, the highlighted symbols don’t reset. Wins hovering above 5,000x is possible here, and it’s really a unique gem that sticks out from the others.
