The scarab beetle is the wild symbol; it will substitute for all of the other symbols to help you form more winning combinations.
Egyptian Emeralds does not feature a scatter symbol.
If you land three stacked wild symbols on reels two, three or four then you will receive a scarab respin. During the respin, the wild symbols from the stack will move to other random position on the reels. It is also possible to retrigger the respin if another stack of wilds land on the reels, and this way it is possible to receive a number of respins with an ever-increasing number of wilds on the reels.
The wild symbol offers the top payout of 200x for landing five across the reels. The yellow gem can payout up to 150x, the red gem up to 100x, the purple gem up to 75x, the blue gem up to 50x, the pink gem up to 25x and the green gem up to 20x.
