Sparky & Shortz Hidden Joules is a slot developed by Play'n GO with an engaging visual design. The game features a 7-reel layout with an RTP of 95.08% and high volatility, offering impressive win potential for players of all experience levels.
At 95.08%, the RTP is slightly below the industry average of ~96%. While this is typical for many popular slots, players should be aware of the slightly lower theoretical return.

About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Sparky & Shortz Hidden Joules features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
