The Gorilla King and Queen symbols are Wild symbols that substitute for all other symbols except Mystery Coins and Scatter symbols. The Gorilla King symbol covers the entire first reel when it lands and triggers all Mystery Coins that are on the reels in the same spin. The Gorilla Queen symbol covers the entire fifth reel when it lands and activates all Mystery Coins that are on the reels in the same spin.
If the King and Queen symbol lands on the reels in the same spin, they both swing around the slot machine and increase the cash prizes before being selected. After the Cash Prizes are revealed, the first swing will increase the Cash Prizes to 10x the bet, unless the revealed Cash Prizes are already equal to 10x, then the first swing will increase them to 20x. Each additional Swing adds 10x to the Cash Prize values.
The Royal Pair increases Cash Wins once during normal play and up to 5 times during Free Spins.
Mystery Coins are special symbols that can land on reels 2, 3 and 4. There are 2 types of mystery coins – gold and diamond. Both types reveal cash prizes of 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x or 10x your stake when activated. The cash prizes of all Mystery Coins activated in the same spin are always the same. A multiplier of x2, x3, x5 or x10 is also attached to the diamond Mystery Coins. If the cash win values are too large to display, they are displayed as multipliers instead.
Landing 3 Scatter symbols in one spin triggers 10 Free Spins. Landing 3 Scatter symbols during Free Spins awards 10 additional spins. Scatter symbols can only land on reels 2,3 and 4. During Free Spins, Mystery Coins are locked on the reels until the end of the feature. If the maximum win in the game is reached, the feature is ended.
