Sparks Online Slot Review
Sparks is presented as a modern, low-volatility slot with 5 reels and wins that can form in one or both directions. Its expanding and cloning wild may help create frequent small combinations, but results are never guaranteed.
Theme and Storyline
Sparks has no traditional storyline. Its futuristic electronic visuals instead set the reels against a space-inspired backdrop, giving the game an arcade-style feel.
Graphics, Sound, and Animation
NetEnt’s online slot, Sparks, features transparent 3D reels and brightly coloured symbols that complement its electric, modern look. Animations play when the expanding and cloning wild appears and when the game switches between win-both-ways and win-one-way modes. A soothing musical theme is paired with electronic effects that react to wins.

Top Casinos to Play Sparks:
Gameplay
The game features 5 reels and 20 paylines, with ‘win-both-ways’ and ‘win-one-way’ options. Changing between the 2 modes leaves the wager unchanged. Under ‘win-both-ways’, combinations can form from reel 5 to reel 1 or in reverse, from reel 1 to reel 5. Each symbol, however, pays half the amount offered by ‘win-one-way’.
For a win from left to right, matching symbols must land on reels 1-2-3 (3-symbol combination), 1-2-3-4 (4-symbol combination), or 1-2-3-4-5 (5-symbol combination). Right-to-left wins require matches on reels 5-4-3 (3-symbol combination), 5-4-3-2 (4-symbol combination), or 5-4-3-2-1 (5-symbol combination). Sparks has 10 regular symbols and a blue wild, which acts as an 11th regular symbol. In this video slot, the wild substitutes for any regular symbol.
When ‘win-both-ways’ is enabled, a wild may complete multiple combinations on the same payline, but only one prize is paid. For example, if a line forms ‘A-A-Wild’ from left to right and ‘Wild-Q-Q’ from right to left, Sparks pays only the more valuable result. Here, ‘A-A-Wild’ (3-of-a-kind ‘A’) wins because it pays more than ‘Wild-Q-Q’ (3-of-a-kind ‘Q’).
Wins are paid in coins, not cash. The ‘Coin Value’ control on the betting panel determines each coin’s value, and ‘Level’ sets the number of coins wagered per spin. The levels range from Level 1 (20 coins) to Level 10 (200 coins).
A slider in the lower-right corner of the betting panel toggles between ‘win-both-ways’ and ‘win-one-way’. The panel also offers ‘Auto Play’ and ‘Max Bet’. ‘Spacebar to spin’ and ‘Quick spin’ are available in the options menu.

Bonuses and free spins
Expanding cloning wilds: An orange, flame-like symbol marked with a red ‘W’ appears on reels 2 and 4. This expanding, cloning wild may stay in place for the following spin. It can extend upward, downward, or vertically across the reels, cloning neighbouring symbols in those directions to create multiple winning combinations. The review describes this feature as fairly common and points to it as a possible source of the game’s largest payouts.
Bet sizes, RTP and volatility
The minimum and maximum wagers per spin are 0.20 and 0.40, respectively. Sparks uses coins for reel wagers, set through ‘Level 1’ to ‘Level 10’. Each level adds 20 coins, for a range of 20-200 coins per spin. Use the ‘Coin Value’ betting control to choose an individual coin’s cash value, from 0.01-0.20.
The reported RTP is 96.54%, which the review compares to figures for many other NetEnt slot games. It also describes Sparks as low variance, saying symbol combinations land repeatedly, especially with ‘win-both-ways’ enabled.
Conclusion
Al Buraq Regina shares Evan Carrington’s supplied assessment of Sparks as a colourful, modern video slot with an appealing look. The choice of ‘win-both-ways’ or ‘win-one-way’ allows players to try both approaches without changing their wager. The distinctive ‘Expanding Cloning Wilds’ feature is another highlight: its regular appearances help make up for the game’s relatively limited bonus offering, though they do not guarantee a win.
