You'll be in for a pleasant shock when you play the Sparks slot from NetEnt as it has plenty of surprises in store for those of you who've never played it before. As well as boasting attractive electricity-themed graphics, the game allows you to decide whether the symbols pay one way or both ways. But, the most exciting feature of this slot is its Expanding Cloning Wilds, which can appear anywhere on Reels 2 and 4 to spread wild symbols horizontally and vertically across the reels. Finally, there's the matter of prizes, and we're sure that you'll be delighted to know that Sparks has the potential to pay out as much as 80,000 coins on any given spin.

More about the Software Provider

NetEnt was founded in 1996 by Pontus Lindwall when it was originally known as Net Entertainment. The NetEnt name was only adopted in 2015. With a growing consumer appetite for high-quality online games, the company developed its own online casino software which is now one of the most used platforms in the world. Net Entertainment has also created a suite of live dealer games which are broadcast live from its studio in Malta, and allow players to enjoy Roulette, Blackjack, and Common Draw Blackjack in multiple languages on desktops and mobiles. Furthermore, NetEnt is also one of the most highly-regarded online slots manufacturers, and its slots portfolio includes Mega Fortune, Gonzo's Quest, Icy Wonders, and Starburst.

Appearance and Sound Effects

Captain Tim Peake, eat your heart out because the Sparks slot will take you to a place where only the most honoured astronauts have ever been – outer space. As you levitate as if performing a moonwalk in the depths of deep space, you gain an extraordinary view of the Earth far below you, as millions of stars and distant planets glow under the purple-pink haze of the sun-like planet that sits behind the game logo at the top of the screen. Relaxing ambient music provides the perfect soundtrack to complement the mesmerising scene that lies before you.

The paytable symbols that line the fifteen positions on the reels are all electricity-themed, and it's hard to describe many of them as anything else but pretty, swirling patterns. There are also five playing card symbols (10, J, Q, K, and A) and a whitish-blue orb with a "W" on it. The most valuable symbols on the paytable are the wild symbol and the red six-pointed star symbol.

Bonuses and Special Features

When you first launch Sparks, you're prompted to pick one of two game modes – Win One Way or Win Both Ways. Both modes cost the same, but the Win Both Ways mode raises the RTP slightly from 96.54% to 96.56%, so we'd recommend choosing it over Win One Way.

The glowing orb marked with a "W" that we mentioned earlier is the wild symbol in the Sparks slots game. Its purpose is to help you make winning combinations by substituting for all symbols except Expanding Cloning Wilds.
While the slot doesn't use a scatter symbol or feature a free spins bonus, it does come with a very nifty feature known as Expanding Cloning Wilds. These are displayed as glowing orange "W" symbols that can appear anywhere on the second and fourth reels. Not only can they substitute for all other symbols in the game, but they can also expand up or down or in both directions before cloning the adjacent symbol from the reel on its left onto the reel on its right. This makes it far easier to create valuable five-of-a-kind winning combinations.


Sparks uses five reels, three rows of symbols, and twenty fixed paylines, and has a high RTP (Return to Player Rate) of 96.54% to 96.56%. The game lets you choose one of two modes - Win One Way or Win Both Ways.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-friendly game controls when played on mobile devices.
