Rules and Gameplay

Embark on an interstellar adventure with Sparky and Shortz Hidden Joules where gameplay unfolds on a captivating 7×7 grid. This slot game challenges players to save the planet Alpha Labori by forming clusters of matching symbols. A minimum of five similar symbols clustered together triggers a win, leveraging a unique cluster pays mechanism. The game is distinguished by its cascading feature, allowing for successive wins from a single spin. Wilds play a pivotal role, substituting for other symbols to forge larger clusters, thus enhancing the potential for substantial rewards.

Bonus Features

The game is replete with innovative bonus features designed to amplify the excitement and winning opportunities:

  • Mega Symbol Transformations: Clusters can evolve into Mega Symbols, incrementing the win multiplier with each transformation, thereby boosting payout potential.
  • Boost Meter: This feature captures winning symbols to progress through levels, each offering increased multiplier values, enriching the gameplay with the prospect of escalated wins.
  • Diverse Wild Symbols: A spectrum of six wild symbols, including the Mega Sparky Wild, introduces various modifiers that can dramatically alter the course of play, from adding mega symbols to clearing less valuable icons.
  • Free Spins Galore: Triggering the free spins round unfolds more opportunities to win, with the boost meter continuing its multiplier enhancement spree, and additional free spins up for grabs.


The game’s visual allure is complemented by an array of symbols, each with its own significance and value:

  • Crystalline Charms: Represented by colorful crystals, these symbols form the lower end of the pay spectrum.
  • Alien Artifacts: High-value symbols depicted as aliens, rewarding players with heftier payouts for larger clusters.
  • Wildcard Wonders: From standard wilds to Special and Mega Sparky Wilds, these icons are game-changers, offering a myriad of ways to win.


The potential for payouts in Sparky and Shortz Hidden Joules is as vast as the universe, with rewards scaling with the size and type of symbol clusters:

Symbol 5-Symbol Cluster 25+ Symbol Cluster
Crystal Symbols $0.10 – $15 $15 – $25
Alien Symbols $0.30 – $0.50 $100 – $250


Traditional paylines are replaced with a dynamic cluster pays system in Sparky and Shortz Hidden Joules where wins are determined by clusters of five or more matching symbols.
