The glimmering symbols and laid back music will keep you relaxed, but the wilds and wins will burst in from time to time to rev up the excitement.

Unlike most slots, Sparks doesn’t feature free spins, but it has exciting gameplay fueled by the special feature called Expanding Cloning Wilds, which will be explained in detail further on in the text. Turn on the light!

Sparks bonus, free spins & jackpot

Sparks slot can be played in one of two ways, left-to-right or win-both-ways. You can switch between these two options at any moment, and they bring a subtle but important difference. Left-to-right pays only in that direction, but the wins are bigger, whereas the win-both-ways has you scoring more often, but the wins are smaller. There are no free spins in this game, but the signature feature will more than compensate. We’re talking about the Expanding Cloning Wilds feature, with a special kind of wild symbol which will do exactly what its name says it will!

This amazing symbol appears only on reels 2 and 4. When it does it will choose which direction, or both, to expand in and turn the symbols above and beneath it into cloning wilds as well. Then, it will copy the symbols on the reel to the left to it onto the reel to the right. This should create a combination of at least three, as you’ll get a match of symbol-wild-symbol on the reels. Sparks also has a regular wild, which can show up at any time, and substitute for all the other symbols except for the expanding cloning wild.
