Doom of Egypt delves into the darker side of ancient Egyptian mythology, featuring mummified pharaohs and powerful gods on its 5 reels and 10 paylines. The game is highly reminiscent of the classic 'Book of' style slots, with the Scarab symbol acting as both the Wild and Scatter. Landing three or more Scarabs triggers 10 free spins, where a special expanding symbol is chosen. This symbol expands to cover entire reels after regular wins, potentially leading to significant payouts, especially if it's a high-value symbol.
