Many slot symbols on slot machines today include what are called Wild Symbols. Wild Symbols are symbols that generally substitute for all other symbols to help make combination wins. Often time wild symbols do not fill in for scatter symbols that trigger bonus rounds and free spin games. There are different wilds for each game so check the paytable of the slot to find out the specific rules that apply. A few types are Expanding Wilds, Standard Wilds, Random Wilds, Stacked Wilds, and Multiplying Wilds and Wandering Wilds.
Triple Magic slot includes a wild that also functions as a multiplier. Spin the triple magic wild in any winning combination and that payout will be tripled. Dolphin Coast slot has a stacked wild symbol making every position on that reel wild. All 5 reels include the stacked wild symbol and will make it that much easier to hit a mega payout.
Mad Hatter slot has an expanding wild symbol that will open up and cover a reel when it combines with a winning combination making more wins. In Mad Hatters slot, the expanding wild only appears on reel number 3.
Jonny Specter slot has what are called “Wandering Wild Symbols” or “Random Wilds,” and appear at random and land on a symbol as a ghost to turn that symbol into a wild one. Finally, a slot game like Dolphin Tale includes what is referred to as an “Extra Wild Symbol.” In this case, the wild is much like a random wild and can appear anywhere on the slot during the free spins game and only on reels 2, 3 and 4.
