Sparks Slot Review

Sparks is powered by Net Entertainment and has 5 reels, 3 rows and 20 paylines. This energy-filled game has a Win One Way mode and Win Both Ways mode where the RTP % (return to player) varies ever so slightly. Playable from 20p to £400 a spin, it’s available to play on mobile and tablet devices too.

You can choose whether to play Win One Way or Win Both Ways – different backgrounds are used in each mode to clear distinguish the difference. The main difference is that the hit frequency (the % of wins) is 21.68% in the Win One Way mode and 36.64% in the Win Both Ways mode – I’m not quite sure difference this makes to the variance though as I’m pretty sure it’s the same.

Anyway, you will come across bright coloured symbols which look electric – it has mesmerising sounds and a neon feel it (like NetEnt’s Neon Staxx slot). Theme wise, it’s in the same category as Starburst, Twin Spin and the aforementioned Neon Staxx – these are very popular games so NetEnt must know what they’re doing.

In terms of features, it’s all about the Expanding Cloning Wild feature – wilds can appear anywhere on the reels and substitute for all symbols except for the Expanding Cloning wild. These will only appear on reels 2 and 4 by the way. When it does, it will clone the adjacent symbol from the reel to the left to the reel on the right – this applies to both Win One Way and Win Both Ways modes.

Simply put, if an Expanding Cloning Wild appears on reel 2 for example, it can take over the whole reel and duplicate the symbols from the reel to the left to the reel to the right. If you get the Expanding Cloning Wild on both reels 2 and 4, you will get 5 of a kind combinations.

Saying that, the maximum win in Sparks is only 20 times your stake in the base game and 400 times your stake with the Expanding Cloning Wild feature – it’s a low to medium variance game so not one I think I will play that often. However, the game play is fast and the graphics/animations are superb. I just prefer a little more bite with titles like Piggy Riches, Spiñata Grande and Dead or Alive more appealing.
