Introduction

Book of 99 is a slot built on the design of older slots with the popular Special Expanding symbols. Back in the day when I roamed my local casinos, these were my favorite and regular slots. I have some very nice memories and wins on the legendary Novomatic slots Book of Ra and Lord of the Ocean. Later on, I played many similar slots across money online casinos, with pretty much every provider having a book slot of their own.

So you can see why I was excited to try Book of 99 by Relax Gaming. I already know what the bonus round will be and what to expect without even trying the game. But I’m always eager to see if the game is tweaked and whether the designers decided to add some surprise to the reels. This was the case with Book of 99 as well. The game follows the general design, but the designers left their own mark on the reels.

Who will enjoy this game?

Slots like Book of 99 are quite popular today, especially after Book of Dead was released by Play’n Go. This slot became very popular across online casinos and brought back the fame of the older book slots. So if you’ve ever played a book slot at the casinos you are sure to be intrigued to check out this game. You can see what it has to offer and you can easily decide whether it’s to your liking or not.

How to Play Book of 99

The gameplay of Book of 99 and similar slots is very simple. There are 5 reels with 3 rows, and a total of 10 active paylines, whose number is fixed. The bets can go from $0.10 all the way up to $100 per spin. To set the game in motion you can use the Spin button or the Auto Play feature. The Turbo Play option is also available if you enjoy faster gameplay.

A Decade of Playing Slots

Yes, I’ve been playing slots for over a decade and I don’t think slots like this one will ever go out of fashion. They are fun to play and can pay big in the feature. In the case of Book of 99, the top win sits at 12,075x the stake. This is a great win to land and every player dreams of hitting it when playing online slots. But Book of 99 can produce great wins in every bonus feature.

My Own Experience Playing Book of 99

The detail that initially attracted me to Book of 99 was the 99% RTP value. This was a bit odd for me since most other similar slots have an RTP value of 96%. But I can’t say that the RTP value is really noticeable as you play the game. You can still go down quite a lot if the bonus rounds pay poorly. My top win for now is only 400x the stake. I can’t seem to get the higher-paying symbols as special ones in the feature, so I always end up with smaller payouts. But I know that in games like this one, all you need is one lucky spin to end up with a big payout.

Bonus Features and Payouts

The main symbol in the game is the Book. It’s a standard Wild symbol and also takes on the function of the Scatter. The Wild substitutes all other symbols from the paytable. What’s a bit strange in this game is the fact that the Wild doesn’t have a payout of its own. In most other Book slots landing 5 Wilds on the screen brings a payout of 200x the stake.

On the left side of the reels, you will see the Collection meter. It starts with 0 and ends with 99. Every wild that lands on the screen is collected to the meter. What’s interesting here is that the collection meter doesn’t reset if you change your bet. You can play the game on higher and lower bets. Once 99 wilds are collected you trigger the free spins bonus. The bet the feature is played on is the average bet you used to trigger the feature.

Free Spins Bonus

Apart from the Collection meter, you can also trigger the free spins instantly by landing 3 or more Wilds anywhere on the screen. When this happens you are instantly awarded 10 free spins, played on the triggering bet. If you land 3 or more Wilds during the bonus you get another 10 free spins.

Before the feature begins a book opens and a random symbol from the paytable is chosen. The only excluded symbol is the Wild. This special symbol will expand each time it lands on the screen. For this to happen you need to land at least 2 of the high-paying symbols and at least 3 of the low-paying ones.

What’s great is that the symbols don’t need to land on adjacent reels or from left to right. So if you land 4 symbols on the last 4 reels they will expand and award payouts of 4 of a kind across all 10 paylines. Of course, the biggest wins in Book of 99 land when you get 5 matching special symbols on the reels, expanding for a full screen of matching symbols.

The top paying symbol in the game has a payout of 500x the stake, so a full screen of them translates to a win of 5,000x the stake.

Comparison with Other slots

Like I already said Book slots are pretty much identical with some small changes. You can compare this game to the Book of Dead, Ramses Book, Book of Ra, Book of Aztec, and Book of Fortune. There are many book slots to choose from across online casinos, so if you like what they have to offer you can give them all a try.

Benefits and Drawbacks

I think it’s nice that you can trigger the feature by collecting 99 wilds. This may seem like a lot but in reality, you can collect them in under 200 spins. If you consider the high RTP and base play wins you can lose around 100x your stake, by the time you collect the Wilds to trigger the feature. So many times you can easily break even or end up in profit thanks to this feature.

Our Conclusion

Book of 99 is an interesting slot from Relax Gaming and is one of the highest-paying online slots 2024 with an incredible RTP of 99%. I like the fact that the designers left a mark of their own, rather than just releasing a clone game. You can give this slot a try across our top casinos for Canadian players and see how you like it. Who knows, maybe on your first few tries you can get a full screen of the higher-paying symbols. Games like this are known to pay big in the feature, so it can easily happen to you.
