The bonus feature begins with you having to pick from 6 ancient crates, all containing different amounts of cash. You can go on until you open the crate with the symbol "Collect". The cash prizes go as high as 4x the bet on the triggering spin.
When you are done with the ancient crates, you will go on to trigger another 6 features. They will appear in the following order:
Number 1 - Scorpion Scatter - is a feature where the Scorpion scatter symbols is turned into an extra scatter that pays even more. This way your chances to land the big wins are highly increased.
Number 2 - Expanding Mummy - here the wild is turned into an expanding wild. The expanding wilds cover the entire reel they appear on, which gives you the shot of a lifetime to collect a massive slot win.
Number 3 - Scarab Attack - during this bonus feature you get to spin with 2 more wild symbols on reels 2 and 4. The wilds appear at random and can make truly amazing wins possible.
Number 4 - Collapsing Reels - is a really cool feature where the winning paylines award you the cash prize, and then they are collapsed and replaced by new symbols (kind of like a re-spin, but for one single reel).
Number 5 - Mummy Power - is a feature where each wild symbol multiply the winnings of the payline by 3x.
Number 6 - Mummy Respin - whenever you land a wild on a reel it will freeze while the other reels keep spinning. These respins will go on until you form a winning combination.
