300 Sheilds



Sparks is an online slot by NetEnt that uses a fascinating theme of electricity to light up your computer monitor or mobile screen with a glorious display of multi-coloured lights. Although on first appearance, it looks very much like a typical five-reel slot, it comes with a clever twist. Most online slots only allow you to create winning combinations from left-to-right across the reels, and a few let you create wins both ways. But, with Sparks, you’re in the driving seat as you can choose between both options, and the great news is, it doesn’t cost any more to take advantage of the both-ways-pay mode.

Just when you thought that the gameplay couldn’t possibly be improved any further, there is also a fantastic feature called Expanding Cloning Wilds. These powerful symbols are not only able to expand up and down each reel, but also clone adjacent symbols to give you guaranteed winning combinations.


NetEnt has gone to great lengths to deliver top-quality graphics as part of the overall playing experience, and the swirling lights that form the pay table symbols look almost like the trails left behind by sparklers on Bonfire Night. You also get to enjoy the beautiful backdrop of the Earth viewed from outer space, and the game logo burns brightly like the Sun at the top of the reels. The soundtrack comes courtesy of relaxing ambient music that makes the feeling of flying slowly through the galaxy an unbeatable experience.

80,000 coins is the game’s top jackpot, and the betting range is designed to suit all kinds of players with its minimum and maximum stake-per-spin of 20p and £400 respectively.

Finally, Sparks comes with two exciting and fresh special features that you can’t help but be impressed with – win one way versus win both ways and Expanding Cloning Wilds.

The circular blue spark marked “W” is the wild symbol, and it can appear on all five reels where it can replace any symbol except Expanding Cloning Wilds.


Expanding Cloning Wilds look exactly like regular wilds, except they’re orange rather than blue. But, they’re more powerful than regular wilds as they can substitute for all symbols including the regular wild. You’ll notice them appearing on Reels 2 and 4, and when you see one on your screen, it may expand in both directions, expand up, expand down or stay the same.

Each Expanding Cloning Wild copies the symbol directly to its left to the symbol on the right so that a three-of-a-kind win is created. When an Expanding Cloning Wild lands on Reel 2 and Reel 4 on the same spin, all of the symbols between them are cloned across the relevant row to form a five-of-a-kind win.
