Sparks is a 5-reel slot with 3-rows powered by NetEnt. It offers 20 pay lines, and the opportunity for players to elect for wins to pay for matching symbols in both directions, or L-R only. This slot is definitely not stacked with features – the main interest lies in the Expanding Cloning Wild which, when it lands, guarantees a minimum of one 3-symbol combination. This happens regularly, and from time to time the feature will deliver a significantly larger win too. Bets range from £0.20 to £400 per spin.
Games
In practice the win-both-or-one-way-only feature is a gimmick, as the difference in RTP between these choices is just 0.02% – symbols are worth 2x when you play one-way-only, but you’re twice as likely to secure a winning combination when you play both ways. On balance, playing both ways seems to deliver more life to the game. Average RTP is 96.5%, and the game plays out well on mobile devices too.
Design
Visually Sparks is a nice-looking slot. NetEnt graphics are always clean and crisp, and the rich black/purple background on Sparks provides the perfect contrast for the animated glowing light-pattern reel symbols. It has a warm and inviting feel. The 10-thru-Ace standard symbols are presented in a cute curly script and blend well with the higher-paying light bursts.
Bonuses and Features
Expanding Cloning Wild – appears on reels 2 and 4. Replaces all other symbols, and can expand vertically up, down, or in both directions. It then clones the symbols on the reel to its L onto the reel on its R, guaranteeing 3-symbol winning combo whenever it appears
