How to Play
Book of Oasis is 1 of those old-fashioned slots, so its navigation is extremely simplified and makes the game looks like a title from the past:
- Let’s begin from the left as there, you will find the first section to select a bet of €0.05 – €100 depending on the number of active lines
- You can switch between 5 or 10 active lines
- After choosing these parameters, push the green icon on the right to make a spin
In addition, you will find a purple ‘Max Bet’ button and an ‘Auto’ icon, which can trigger up to 250 rounds in a row.
Book of Oasis RTP and Volatility
The high volatility of Book of Oasis is supplemented by the RTP of 96.15%.
The RTP of 96.15% will suit you as it’s high according to modern gambling standards. If you aren’t into taking risks, this slot isn’t your choice. As its variance is high, it is not that easy to collect wins and you need more patience and money to keep on playing. However, only high-volatility titles can provide massive rewards.
Theme
Dr. Jeffrey Robertson, a well-known traveller, has started his new journey to find the book, which will let him open the hidden underwater temple. Actually, it’s another Egyptian-themed slot, so all its design is built around this mysterious land. The reel set can be found in front of the Nile and surrounded by both trees and stone buildings. Arabian music and golden columns next to the grid make the atmosphere so mysterious, bringing players to the land full of secrets and riches of pharaohs.
A standard layout of the 5x3 size with 10 winning lines displays symbols you could meet on other Egyptian-themed slots. Four card suits are paying up to 20x. A purple flower is providing more as its value is up to 50x. Golden ankhs and jars pay up to 150x. The pharaoh will greet you with a prize of 1–400x, while the archeologist, the main character, is paying 2–1,000x for 2–5 symbols. A book with sacral inscriptions is both a Wild and a Scatter, which pays up to 200x.
Mobile Compatibility
If you remember old Egyptian slots that used to stand in land-based casinos or those games launched online but only on certain devices, you will be glad to find out that today, modern games don’t require all these things. As HTML5 is used to produce these games, their features are mobile-optimized regardless of whether you are an iOS or Android user.
About Gamomat
Gamomat emerged in 2008 and has been working a lot to make its portfolio packed with interesting games that are rich in bonuses. And the team managed to do it as today, over 130+ games from the vendor are found at the lobbies of great online casinos in a range of regulated markets. Many of them are based on old-school machines, so a portion of nostalgia is guaranteed.
You may play Royal Seven Ultra, Lava Lions, and other games. An interesting fact about the vendor is that it’s eco-friendly as Gamomat donates a part of its revenue each time to protect the climate. It doesn’t influence payouts and players receive what they have to.
Bonus Rounds & Free Spins
Like many other ‘book of’ slots, this one has similar mechanics and its bonuses will be understandable to those who remember the previous variations of this game.
Free Spins
As the book serves not only as a Wild but also as a Scatter, 3 to 5 symbols of it activate 10 free games. Any regular symbol is selected to be a bonus one. The feature is retriggerable, but once you get more spins, a new bonus symbol isn’t selected again. When 2 to 3 bonus symbols occur on the reels and they are involved in winning positions, these symbols are stamped to cover the entire reels.
Gamble Feature
Those who think that their wins aren’t high enough should opt for a gamble option. It’s optional and available in 2 variations:
- Card Gamble. When you activate this feature, try to guess the colour of the face-down card on the screen
- Ladder Gamble. Its concept is either to increase or decrease your prize, and you can collect or continue after you win
Book of Oasis Demo Play
The free version is a good practice before a real game. Or it’s a chance for players to simply relax and Dr. Jeffrey Robertson to explore new lands. At any rate, the free version will provide you with all the necessary options so that you can feel like a real gambler and understand how these features work.
Max Win
Wins of 5,000x aren’t the highest, but the score is good for a slot with simple mechanics.
Yes, the 5,000x winning limit can’t be called a high one, but taking into account the lack of more advanced bonus options and the old-fashioned style of the game, it seems to be matching this machine.
Overall Rating
If you like books about Egypt or enjoy games based on these plots, Book of Oasis will please you. The bonuses in the form of free spins and special symbols are normal as well as the top winning amount of 5,000x. Frankly, it’s just 1 more ‘book of’ game, but if you are missing these old-school games, then why not?
