Why Play Danger High Voltage
Symbols & Features
The slot has 10 standard symbols, six of them are card values, ranging from 9 through to A. Some of the remaining symbols are based on things to do with Mexico, namely a taco and a Day of the Dead skull; the other two are a bell and a disco ball. The slot also has a scatter symbol, a crowned heart with a Top Desire banner across it; land three of more scatters and you’ll get to choose between Voltage Free Spins and Gates of Hell Free Spins. There are also two different kinds of wild: there’s a standard wild, as well as two full length ones that take up the whole reel.
Full Reel Wilds
There are two full reel wilds: Wild Fire and Wild Electricity. Both can appear on reels 2 and 5 only. Whenever one of them appears, it substitutes for all other symbols apart from the scatter. Should you land the Wild Electricity symbol, your winnings will be multiplied by six.
