About Sparky and Shortz Hidden Joules Slot 

Sparky and Shorts Hidden Joules slot from Play’n GO is an exciting sequel of their previously popular game from a couple of years ago.

The game introduces 7 reels and 7 rows in this thrilling sequel, providing excellent opportunities for compelling gameplay. Unlike its predecessor, the paylines now feature the Cluster Pays mechanic, where you can win by connecting five or more symbols horizontally or vertically.

Whether you’re a high roller or prefer more conservative bets, this game caters to all players, with a minimum bet of 0.10p and a maximum bet of £100 per spin.

Design, Symbols, and Graphics

Get ready for an expanded grid in this captivating robot sequel, as the Sparky and Shortz Hidden Joules slot unveils seven reels positioned on the belly of Sparky, the larger of the dynamic duo. 

Adorning his right shoulder is the game’s logo, while on the left, you’ll find the win multiplier starting at 1x. Look below, in the bottom right corner, and you’ll spot the vibrant red-coloured Sparky, brimming with energy.

You’ll encounter a few symbols with varying payouts as you explore the game. The lower-paying symbols consist of five crystals, each boasting a unique shape and colour. Keep an eye out for the blue circle, green rhombus, pink drop, red square, and orange hexagon, as they can reward you with payouts ranging from 15x to 25x your bet when you achieve wins containing 25 or more symbols.

The higher-paying symbols showcase three intriguing aliens. Look out for the one-eyed octopus-like creature, the green frog-like being, and the red three-eyed extraterrestrial. These extraordinary beings can award payouts from 100x to 250x your bet.

Finally, the Sparky and Shortz Hidden Joules slot introduces various Wild symbols that substitute for all other symbols, assisting you in creating winning combinations.

Gameplay and Features on Sparky and Shortz Hidden Joules Slot

One thing that makes the gameplay enjoyable in this slot is the availability of several Wild symbols. There are other extras as well, so here they are explained. 

Cascading Wins

You can achieve multiple wins in a single spin with cascading wins. When you complete a winning combination, the winning symbols disappear, and new ones replace them on the reels. 

If you create another win after the grid gets refilled, the process continues, with new symbols replacing the winning ones. The cascade of wins can continue as long as you make winning combinations.

Boost Meter & Win Multiplier

The Sparky and Shortz Hidden Joules slot features a Win Multiplier that starts at 1x and has the potential to grow up to 25x. When regular-paying symbols form a 1x4, 4x1, or 2x2 formation, they transform into Mega Symbols while increasing the Win Multiplier by 1.

The game also introduces a Boost Meter that accelerates the increase of the Win Multiplier. The Boost Meter progresses to 2+, 3+, 4+, and 5+ levels when you win 25, 60, 110, and 200 symbols, respectively - reaching the top level of the Boost Meter results in the Win Multiplier increasing by 5x each time a Mega Symbol gets created.

Sparky and Shortz Hidden Joules Slot Feature

Wild Symbols

The slot features a total of 6 different Wild symbols. These include one regular Wild symbol, 4 Special Wild symbols, and the Mega Sparky Wild symbol.

When a special Wild contributes to a winning combination, it gets collected. Once there are no more cascades, the collected special Wild activates its unique feature. Here are the actions performed by each special Wild:

  • Red Wild - adds Mega Symbols randomly onto the grid;
  • Yellow Wild- removes all lower-paying symbols from the grid;
  • Purple Wild - creates random regular Wild Symbols on the grid;
  • Green Wild - destroys a randomly selected pattern across the grid, possibly replacing some symbols with a single symbol.

To unlock the Mega Sparky Wild symbol, you need to collect four special Wilds. This symbol is equivalent to a 2x2 regular symbol in size. It’s possible to trigger the Mega Sparky Wild thrice in a single spin. 

The Sparky Wild gets added along with a Special Wild on the first trigger. The Sparky Wild will get added with either a Special Wild or a regular Wild on the second trigger. Finally, the Sparky Wild is always present with a regular Wild on the third trigger.

Other Play’N GO Slots

Play’n GO is a well-known name you’ll often see in online casinos. They provide fantastic technology and a wide range of games. They’re among the top video slot developers, creating many of them. We have plenty of reviews on their games, including Free Reelin Joker 1000, Highway Legends, and Viking Runecraft Apocalypse

Our Verdict 

Sparky and Shortz Hiden Joules is a remarkable sequel to the popular 10-payline game from 2021. Once again, Sparky takes on the role of the game’s host, with the entire grid displayed on his robot stomach, while Shortz runs the show uniquely. 

What sets this game apart is the absence of traditional paylines, as you now achieve wins by connecting five or more symbols horizontally or vertically. This innovative approach and advanced graphics create an immersive and modern gaming experience.

One significant change from the previous game is replacing the Free Spins Feature with 4 Special Wild Symbols that contribute to valuable wins in different ways. While some players may miss the Free Spins, others will appreciate the variety of Wilds. 

It may come as a surprise that the game developer chose to decrease both the maximum win and volatility compared to the previous Sparky & Shortz adventure. However, it’s important to note that players still have the chance to win up to 6,000x their bet.
