Pyramid Strike: Slot Verdict Players familiar with 9 Masks of Fire or its many imitators will be well prepared to take on Pyramid Strike. Stakelogic has stuck close to Gameburger's pgslot in most regards, so there are no major, or even minor, discoveries to be made. On the plus side, Pyramid Strike is quite striking graphically, which improves the user experience, but aside from aesthetics, the game doesn't really add much that players didn't have access to before.
