Game overview
What is Crystal Skull?
Will you find the last remaining crystal skull? Filled with adventure and twists, join a daring antiquities explorer who's on a quest to find the last of all lost secret crystal skulls for his exquisite artifact collection. Legends say that each skull has mystical elements that can be used to your advantage to win as big as you can dream. Some people believe that skulls are a proof of extraterrestrials' visits and that they might contain some secrets of our world that were once protected by Ancient Mayan civilization. This is a 3-row, 5-reel, 25-payline slot. Among the symbols on the reels, you'll find a crystal skull which acts as a Wild. The Wild substitutes for all symbols except for the Bonus. It appears on reels 2, 3, and 4 and expands vertically to complete combinations. The Wild completes combinations with the Scatter and doesn’t expand in these combinations substituting for only one Scatter per reel. Scatter symbols count on any position on the reels. 3 Scatter symbols trigger the Bonus Game Wheel of Fortune. It will appear on reels 3, 4, and 5 only. Once you enter the Bonus Game, the wheel starts rotating and stops at a random position. It could be a certain multiplier of the total bet – from x10 to x25, or Bonus section activating the Treasure Hunt Bonus. The player has 3 attempts to try to get the maximum multiplier. In the Treasure Hunt Bonus, there are 5 levels of 5 stone skulls. Skulls hide either treasure or ancient snakes. You can check a skull per level. All wins received during the pick game are added up. The Bonus cannot be won again during the feature. It’s impossible to get back to the Wheel of Fortune Bonus Game from the Treasure Hunt Bonus. Players can double their winnings up to 10 times during the Classic Risk Game. Bonus Pop is also available in this game. Will you unravel the story for yourself? Will you manage to find the last remaining skull? Don't leave any stone unturned in Endorphina's newest Crystal Skull slot!
