Sparky & Shortz Hidden Joules Slot Overview

Sparky & Shortz Hidden Joules is a new casino slot from Play’n GO with two robots as the main characters. We were first introduced to these charismatic droids in Sparky & Shortz, where they go all in to save their home planet Alpha Labori. In this sequel, the 10 paylines have been exchanged, and you’re awarded wins by landing 5 or more symbols connected horizontally or vertically. There’s also a win multiplier that can grow up to 25X when you’re making wins and 4 different special Wild Symbols that perform unique actions for you. Let’s go; Sparky & Shortz are waiting for you.

Base Game

Sparky & Shortz Hidden Joules is a video slot from Play’n GO with 7 reels and 7 rows. Wins are made by landing at least 5 symbols connected horizontally and/or vertically. The Min.bet is 0.1, and you can place up to the Max.bet of 100. The default RTP is 96.20%, but Play’n GO is, as usual, also releasing versions in other RTPs of 94.20%, 91.20%, 87.20%, and 84.20%. The volatility is mid-high (7/10), and the max win is capped at 6,000X the bet. The probability of scoring the max win is 1 in 15 million spins.

On planets far, far away from Earth await features such as Cascading Wins, Boost Meter & Win Multiplier, and Wild Symbols.

Sparky & Shortz Hidden Joules Slot Information

The grid has been expanded to 7 reels in this robot sequel, and they’re positioned on the stomach of Sparky, the bigger one of the two droids. The game’s logo sits on his right shoulder, and on the left is the game’s win multiplier, which starts at 1X. Below him, in the bottom right corner, stands the red-colored Sparky. You make wins by connecting at least 5 symbols of the same type horizontally and/or diagonally. The game is available on mobile phones and other digital devices.

The lower-paying symbols are 5 chrystals in different shapes and colors. The blue circle, green rhombus, pink drop, red square, and orange hexagon award between 15X and 25X the bet for a win containing 25 or more symbols. The higher-paying symbols are 3 aliens. The one-eyed octopus-looking one, the green frog-looking one, and the red three-eyed one award between 100X and 250X the bet. The different Wild Symbols substitute all other symbols in making wins.

Sparky & Shortz Hidden Joules Slot Features

What is the max win in the slot Sparky & Shortz Hidden Joules?

You can win up to 6,000X the bet.

What features are available in the slot Sparky & Shortz Hidden Joules?

The features are Cascading Wins, Boost Meter & Win Multiplier, and Wild Symbols.

Big Win

Cascading Wins

It’s possible to make several wins on one spin. As soon as you land a winning combination, the winning symbols disappear, and new ones are added to the reels. If you can make a new win once the grid is refilled, those winning symbols are also removed while new ones are added. The cascades continue as long as you keep on making wins.

Boost Meter & Win Multiplier

There’s a Win Multiplier starting at 1X, possibly growing up to 25X. Landing any regular-paying symbols in a formation of 1x4, 4x1, or 2x2 will turn them into Mega Symbols. Each transformation increases the Win Multiplier by 1.

There’s also a Boost Meter that can speed up the Win Multiplier increase. It grows to 2+, 3+, 4+, and 5+ whenever you have made wins with a total of 25, 60, 110, and 200 symbols. Having the Boost Meter on the top level means that the Win Multiplier increases by 5 every time a Mega Symbol is created.

Wild Symbols

There are 6 different Wild Symbols: 1 regular, 4 Special, and the Mega Sparky Wild. Every time a special Wild takes part in a win, it’s collected, and its special feature is activated when no more cascades are made. These are the actions the special Wilds perform:

Red Wild = Randomly adds Mega Symbols on 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, of which some might be replaced by one symbol.

The Mega Sparky Wild is created when 4 special Wilds have been collected. The symbol is the size of 2x2 regular symbols. The Mega Sparky Wild can be created up to three times on the same spin. On the first trigger, the Sparky Wild is added along with a Special Wild. On the second trigger, the Sparky will be added with either a Special or a regular Wild, and it will always be added with a regular Wild on the third trigger.

Sparky & Shortz Hidden Joules Slot Conclusion

Sparky & Shortz is a worthy sequel to the 10-paylines game released in 2021. Sparky is once again the host of the game, having the entire grid on his robot stomach, and Shortz is running the show in his way. There are no paylines in this game; wins are instead made by connecting 5 or more symbols horizontally and/or vertically. It makes the gaming experience feel as modern as the advanced graphics.

Another notable detail is that the Free Spins feature from the previous game has been replaced by 4 Special Wild Symbols that help you make valuable wins in different ways. Some people might miss the Free Spins, while others will appreciate the abundance of different Wilds. Collecting 4 Special Wilds will also produce the 2x2 Mega Sparky Wild, which could be your ticket toward riches.

It might surprise you that the game developer has chosen to decrease both max win and volatility from the previous Sparky & Shortz adventure. You can take home 6,000X the bet, and the probability to land the max win is one in 15 million, which is better stats than in many other casino slots with higher max wins. For the players who prefer bigger maximum payouts, we can recommend Fantasma Games’ robot slot Twisted Turbine.

Sparky & Shortz Hidden Joules from Play’n GO is an intense space adventure with two robots.
