Gridlock Gem Blast Slot 


April 2025 saw the Gridlock Gem Blast slot enter the casino scene, a Switch Studios creation that is filled with jewels and vibrant visuals. One of the main ways in which this creation separates itself from other online casino slots, though, is through the inclusion of a cluster pays game engine. Instead of paylines, groups of adjacent symbols determine outcomes, with additional locking symbols and multiplier mechanics being added to the Gridlock Gem Blast slot to make it all the more unique.

Gridlock Gem Blast Game Background 


The playtable in the Gridlock Gem Blast slot is like the ones found in Slingo games, with it consisting of 5 vertical reels and 5 horizontal rows of symbols. As we have already emphasised, there are no paylines here as Switch Studios have opted for a cluster pays system which determines combinations if 4 or more matching symbols land adjacent. All 25 symbol segments sit inside a gold frame, and off to the left of the Gridlock Gem Blast slot, a progressive multiplier metre has been positioned. 

Taking a look behind the reels, this is filled with a purple spiral pattern that centres in towards the playgrid. This creates a vibrant appearance for the Gridlock Gem Blast slot, with the golden game logo contrasting with the backdrop as it sits above the reels. Titles such as Gems Inferno Megaways and Diamond Charge Megaways also feature gemstone visuals; however, the style of the title at hand remains distinct.

Gridlock Gem Blast Slot Symbols 


Another way in which the Gridlock Gem Blast slot defines itself is through its small selection of symbols that could land across the reels. There are just 5 of these that make up the paytable, all of which are different coloured gemstones, something you could likely deduce from the name of this title alone.

Lower Value Symbols:
Yellow Gemstone
Green Gemstone

Medium Value Symbols:
Red Gemstone
Purple Gemstone

Higher Value Symbols:
Diamond Gemstone

Switch Studios has added another 2 bonus symbols to the Gridlock Gem Blast slot; however, these do not possess any value of their own. Instead, these are a rainbow crystal wild and a golden lock scatter, the latter of which could potentially trigger the titular Gridlock feature that defines this release.

Gridlock Gem Blast Bonus Features 


Although it is not necessarily a bonus, it is worth mentioning the blank playtable spaces in this Gridlock Gem Blast slot. There are a total of 25 symbol sections that make up the playgrid; however, not all of these are filled with gemstone symbols in each spin. Instead, some digital ‘X’ places could appear, with these essentially acting like blockers. These hold no value and instead take up space where other gems could have landed.

Moving to a more standard bonus feature, the rainbow crystals in the Gridlock Gem Blast slot are wilds. This means that if they are landed, these are able to substitute in place of any other gemstones, potentially forming clusters if landing adjacent to any matching symbols.

The last of the bonuses in the Gridlock Gem Blast slot is the most inventive of the bunch, that being the ‘Gridlock Games’ feature. If a golden lock scatter is landed adjacent to a cluster of gemstones on the reels, this could trigger the bonus round. In this, the triggering symbols lock in place, with only these coloured gemstones and blank spaces appearing on the reels, just like Sunny Fruits 2 Hold & Win. At the start of the ‘Gridlock Games’, the triggering golden lock is assigned a heart with a number between 3 and 5. This indicates the number of lives the symbol represents. 

In the following spins, if any gemstone symbols are landed, these lock in place on the screen. At the same time, this could cause the multiplier metre next to the reels to increase, similar to the feature found in Wins of Mermaid Multi Power. If these symbols are not connected to the golden lock cluster, though, this causes the scatter to lose a life. These spins repeat until no further gemstones are landed or if the golden lock loses all of its lives.
