Even though there are plenty of slot games inspired by Ancient Egypt, you will find that there are many surprises, as well as special features that make Osiris a great slot worthy of your attention. You will feel like you've stepped into a sacred temple thanks to the background which actually depicts the interior of an Ancient Egyptian temple. Even though the graphics is not outstanding it is pretty decent and does a good job of capturing the atmosphere of the game.

In terms of the soundtrack, it's definitely inspired by Egypt, and you will enjoy your atmosphere accompanied by appropriate sound effects.

There are 12 symbols including the low-win card royals, symbols based on Ancient Egypt and a scatter (Osiris), and a wild (Ausir).
