There are two wild symbols, the skull and the flaming skull, both of which will substitute for all of the other symbols, except for the scatter symbol, to help and form winning combinations.
The scatter symbol is a treasure chest.
The Skulls Up! Respin begins whenever a flaming skull wild symbol lands on the reels. It will move up into the lowest position of the flag above the reels, opening up that position and increasing the number of paylines. You then receive a respin with the extra paylines active and if another flaming skull lands then the process repeats itself. After one spin, the flames die out and the skull drops away, and the paylines return to normal when there are no skulls left on the flag. If you manage to land enough skulls, then there will be 1944 ways to win.
The Flaming Free Spins begin when the treasure chest scatter symbol lands on reels two, three, and four simultaneously. You will win up to six free spins during which the Skulls Up! Respins are still active. However, during the free spins, the increased reel positions will remain in play for the duration of the spins. Better yet, two extra spins are awarded for each reel that reaches the maximum height of six positions.
