Sparky & Shortz Hidden Joules is an online slot that was developed by Play’n GO and released at the end of June 2023. The game follows droids Sparky and Shortz as they embark on a mission across the galaxy to rescue creatures and preserve materials.
A sequel to the original Sparky & Shortz slot, the new game is set on an alien planet with the grid on a droid. Symbols in the Sparky & Shortz Hidden Joules slot include five types of wild icons, as well as red, green, and blue aliens, and orange, red, purple, green, and blue materials.
The Sparky & Shortz Hidden Joules slot uses a 7×7 grid layout with a cluster pays mechanic, which requires you to make clusters of five or more identical icons to make wins. The game requires a bet of between £0.10 and £100 per spin, and it provides you with a chance to win up to 6,000x your bet.
The highest-paying symbol in the Sparky & Shortz Hidden Joules slot is the red alien, which pays £50 for a cluster of five icons, £100 for six icons, £200 for seven symbols, £350 for eight icons, £500 for nine icons, £1,000 for 10 to 11 symbols, £2,000 for 12 to 14 icons, £5,000 for 15 to 19 symbols, £12,000 for 20 to 24 icons and a maximum of £25,000 for 25 or more symbols.
After the above, the green alien pays £20,000, the blue alien pays £10,000, the orange and red materials pay £2,500, and the purple, green, and blue materials all pay £1,500 each.
The Sparky & Shortz Hidden Joules slot has an RTP of 96.2%, which is around average for most video slots. The RTP (Return to player) is a percentage rate that informs you of how much of all wagered money is returned to players over a long period of time and over numerous players.
The game also comes with medium to high volatility, which means wins are skewed towards the larger but infrequent side. This can make the game better suited for experienced slot players and high-rollers or anyone with a larger bankroll.
The Sparky & Shortz Hidden Joules slot comes with numerous special features. For example, there are wild icons that substitute for all symbols to help make more wins.
There are an additional five wild icons, including four special wilds and one mega Sparky wild. Special wild icons are collected and trigger unique features; red wilds randomly add mega symbols to the grid, yellow wilds remove crystal symbols from the grid, purple wilds add basic wilds to the reels, and green wilds destroy and replace a pattern of symbols with a randomly selected icon.
When four special wild icons have been collected, the Sparky wild is added to the grid with an ordinary wild when there are no more cascades. This can be triggered up to three times by collecting four special wild symbols. On the first trigger, a Sparky wild is added to the grid with a special wild. On the second, a Sparky wild is added with a special or basic wild. On the third trigger, a Sparky wild is added with a basic wild.
On random, non-winning spins, special wild icons are added to the grid in positions adjacent to a transformed mega symbol.
Landing alien or material symbols in a 2×2, 4×1 or 1×4 shape will transform the clusters into mega symbols. Each transformation increases the icon’s win multiplier by +1 and can increase up to 25x.
Wins made in the slot trigger cascades, where winning symbols are removed, and new icons fall to replace them. These icons can make more wins, continuing the reaction until no more wins are made.
The game has a boost meter, which is filled by forming winning combinations. There are four stages; +2, +3, +4, and +5. Each stage requires you to form clusters of 25, 60, 110, and 200 symbols, and each of these modifies how much transformations increase the win multiplier.
There are several games similar to the Sparky & Shortz Hidden Joules slot, all of which are based on droids. One game is Wild Robo Factory by Yggdrasil, which uses a 5×4 grid layout with 25 paylines and an RTP of 96.4%. Icons in the slot include robot parts, playing card suits, and plenty more. When it comes to special features, the game comes with a free spins mode, swapping symbols, re-spins, and more.
Another game worth checking out is Wild-O-Tron 3000 by NetEnt, which uses a 5×3 grid layout with 20 paylines and an RTP of 96.01%. Symbols in the slot include various coloured robot parts, and the special features in the game include wild icons and stacked symbols.
