Gameplay
There are 5 reels and 20 pay lines, and you have the choice to play them using either âwin-both-waysâ or âwin-one-wayâ. Making the switch between these 2 options will not increase or decrease your bet amount. The advantage of playing win âwin-both-waysâ is that you can win when the slot lines symbols up from reel 5 to reel 1 and from reel 1 to reel 5; however, the value of each symbolâs payout is half the paid out while playing âwin-one-wayâ.Â
Symbols that line up from left to right must be on reels 1-2-3 (3-symbol combo), 1-2-3-4 (4-symbol combo), and 1-2-3-4-5 (5-symbol combo). Symbols that line up from right to left must be on reels 5-4-3 (3-symbol combo), 5-4-3-2 (4-symbol combo), and 5-4-3-2-1 (5-symbol combo). There are 10 regular symbols in total and a blue wild symbol that makes up for an 11th regular symbol. The wild symbol is the Sparks video slotâs wildcard and substitutes for any of the regular symbols.Â
While playing âwin-both-waysâ, if the wild completes multiple combinations on the same pay line i.e. âleft to right win A-A-Wildâ and right to left âWild-Q-Qâ, then only the highest symbol combination will pay. In this example, the Sparks slot would only payout for the A-A-Wild (3-of-a-kind âAâ) combination as it has a higher value than the âWild-Q-Qâ (3-of-a-kind âQâ) combination.Â
All combinations wins are paid out in coins and not cash. In order to set the value of each of your coins, use the âCoin Valueâ box on the betting panel. To set the number of coins you would like to wager per spin use the âLevelâ option which starts at Level 1 (20 coins) and goes up to Level 10 (200 coins).
You can switch from âwin-both-waysâ or âwin-one-wayâ using the slider at in the bottom right-hand corner on the betting panel. You also have âAuto Playâ and âMax Betâ options on the betting panel. For âSpacebar to spinâ and âQuick spinâ, use the options menu.Â

Bonuses and Free Spins
Expanding cloning wilds: There is an orange firey symbol with a red âWâ on reels 2 and 4. This is the cloning expanding wild. This symbol can be a sticky wild and stay on the reels for the next spin, it can expand down the reels, up the reels, or vertically across the reels. Its job is to clone adjacent symbols in any of these directions in order to create multiple symbol combination wins. It is also a feature that is quite common and will be the source of your largest payouts.
Bet sizes, RTP and Variance
The min-max bets are 0.20 to 0.40 per spin respectively. The Sparks online slot uses coins to make bets on the reels. Coins are configured by selecting âLevel 1â to âLevel 10â. Each time you increase the âLevelâ, 20 coins will be added to the spin. Therefore, the min-max coins per spin is 20-200. The cash value of each coin can be set from 0.01-0.20 using the âCoin Valueâ betting option.Â
The RTP on your bets is expected to be 96.54%, which is similar to most other NetEnt slot titles. And, this is a low variance slot game because the Sparks online slot has a habit of continuously linking up symbol combinations â especially if you use the âwin-both-waysâ feature.
Conclusion
We really like the look and feel of the Sparks video slot title. It is modern, attractive, and colourful. Having the option to choose between âwin-both-waysâ and âwin-one-wayâ is an excellent feature that allows you to experiment with which one you prefer without having to increase or lower your spin bet commitment. Finally, the unique âExpanding Cloning Wildsâ feature is actually more than enough to make up for the lack of bonus features thanks to its regular appearances on the reels.
