To stand out in the crowded world of slot machines, developers need to be creative. For example, choose an unusual theme or come up with innovative bonus features that no one else has seen before. The Relax Gaming developer followed a learned scenario. As you can tell from the name, Book of 99 is another "Book" slot machine.
This time the action takes place in Ancient Greece. The playing field, consisting of 5 reels in 3 rows, gives 10 paylines, using which you can reach the maximum win of 5,000x your bet. The betting range here is from 0.10 to 100 coins and bonus features include Free Spins, Wilds, Scatter, and Expanding symbols.
An interesting step on the part of the provider was the addition of an attractive RTP value of 99%, which refers to the name of the slot, as well as the addition of a generous collection system. The volatility is high, so you have the opportunity to compete for a big prize.
In this Greek odyssey, you will find a group of unpaid symbols: Ace and King pay up to 15x if you land five, whereas Queen, Jack, and Ten pay up to 10x, Jack pay up to 10x your bet.
The higher-paying characters are the Baby Eater Monster Lamia – up to 75x your bet, Cyclops – up to 75x too, as well as female protagonists up to 20x and male protagonists up to 50x. The book is a special Wild symbol that pays nothing, rather substitutes for all symbols except the special expanding symbol in Free Spins.
As always, you need the Book to activate the best moments of the gameplay. Not only is this Wild, a substitute symbol for completing prize combinations, but Scatter – 3 or more gives you a round of 10 free spins, but without additional payments, which is a little unusual. Before the start of the bonus round, one of the standard symbols is randomly selected as an Expanding symbol for the duration of the feature.
Finally, let's take a look at the next feature, the Wild Symbol collection system. For each Wild symbol landed in the base game, the scale near the playing field is increased by 1 time. Filling the counter with 99 collected Wilds will earn you a round of 10 free spins. The launch takes place according to the same rules, so Expanding symbols come into the feature.
A well-developed theme of ancient Greek mythology, combined with attractive bonus features, does the trick, and the gameplay attracts you in just a few minutes.
A very volatile action takes place on a classic playing field, consisting of 5 reels and 10 ways to win. Bets can be set from 0.10 coins to 100 coins on any device. Starting on the first reel, bonus combos are generated when matching symbols are placed next to each other on a payline. On the playing field, you will find a group of 10-A characters and higher-paying characters, including the heroes of ancient Greek mythology: Lamia, the Cyclops, as well as the main female and male characters.
The appearance of the slot is great for such a theme, and the bonuses are quite good. We would like to say about the main advantage – RTP. We opened our eyes wide when we saw such large numbers. Well, the provider is countering the downward trend by blessing a new slot machine with 99% RTP. Call it what you want – a tricky move or a gimmick to attract players, but at the end of the day, it's a feature that makes Book 99™ more desirable than many “Book” slots.
In this new slot machine, the maximum theoretical win is as much as 5,000x the stake!
Three or more Book symbols give you a round of 10 free spins. Also, for each Wild symbol landed in the base game, the scale near the playing field is increased by 1 time. Filling the counter with 99 collected Wilds will earn you a round of 10 free spins.
Yes, you can get acquainted with the slot machine for free by launching it in the Demo version.
No, there is no progressive jackpot in this release from Relax Gaming, but you can compete for it in other slots from the same company.
