We must highlight an interesting feature of the game, its special wild card Expanding Cloning Wild, which has the ability to clone symbols, making the chances of winning a prize between the drums increase greatly. It has 5 drums, 3 rows and 20 pay lines. Usually they are only taken into account to count the prize from left to right, but in this game they will give us a choice, if we want to play sideways or both or as they call it in NetEnt, Win both ways. Colored drawings without a specific shape are the special Sparks symbols and the best paid symbol set. The one of greater value is the one of red color that remembers in its form to the classic representation of an atom. For five of this online payment we will get 200 coins. Then, in descending order of value comes orange, green, lilac and blue that give us five coins for five of this. The group of least value are the symbols A, K, Q, J and 10. In addition to these ten standard symbols, there are two special symbols, 2 different types of wild cards. A normal wild symbol that functions as a regular wild card and replaces all symbols except the Expanding Cloning Wild that are just the other type of wild card and will be responsible for activating the special function of the game.

Sparks is a vibrant slot machine prepared by the Swedish slot supplier Net Entertainment. It feels like NetEnt tried to copy their enormous Starburst achievement, by making slot machines through a simple gameplay as well as no bonus game of Free Spins. That being said, Sparks let the players select if they want to play one way or two ways. This means that you could win as normal from left to right, or moreover from right to left. There is also an exciting wild clone feature accessible. The greatest potential win through both normal play as well as both ways play is the similar win of 400x the stake per spin. The payout proportion for Sparks is 96.54%.
