Pharaoh's Tomb slot by Greentube has a classic 5-reel, 10-payline setup and invites you to uncover lost treasures of ancient Egypt.
Landing three Tomb Scatters will award 12 free spins with the symbol upgrade feature - Wild that lands during the free spins turns into a sarcophagus and releases the most valuable symbols. The symbols with the lowest value are removed from the reels and replaced by the next highest. This process is repeated every time a Wild symbol is unlocked. You can also extend the bonus round either by getting the scatter symbols or a Wild which can trigger up to 4 additional free spins.
