Diamond Vortex Bonus Features

If you’ve been craving a slot with a myriad of weird and wonderful bonus features, then buckle up. Diamond Vortex is jam-packed with some peculiar elements that will make your head spin and pull you deeper into a whirlwind of big wins.

Just like the bonus features, the hexagonal grid itself here is an unusual play area. It comes with three concentric circles sharing one permanent wild in the centre. Each ring contains a Zone and a Spot with the latter fixed at the bottom and the former at the top of each ring. It sounds confusing, but it will all make sense when you play the slot.


Diamond Vortex is home to two wilds, the core and sticky, both of which substitute for all paying symbols except bonus symbols, Zones and Spots. The core wild always sits in the heart of the hexagonal grid, while the sticky wilds can appear during any cascade with regular symbols. When sticky wilds drop, they leap from one ring to another inward, edging themselves closer towards the permanent wild symbol.

Rotate Feature

This is when things get moving in the Diamond Vortex slot. On every winning spin, winning symbols get removed from the grid. As the new symbols are being added, the three rings start shifting in a different direction. The inner and outer rings rotate clockwise while the middle ring rotates anticlockwise creating a somewhat mesmerising motion.

Consume Features

Things can get pretty creepy in space when a leaping sticky wild crosses over the rings into the very core of the vortex. Each time a sticky wild reaches the centre, it gets consumed by the core wild, this way increasing your multiplier by 1x up to a max of 20x.

Transform Features

Activated when a Zones meets the Spot on its ring, the feature picks and turns any odd symbols on that ring into matching symbols creating a new winning cluster in the process.

Free Spins

Catching a bonus symbol in a Zone initiates the free spins round. Each bonus symbol caught awards 5 free spins with more spins available during this session.

Diamond Vortex Jackpot

Even without a jackpot, the Diamond Vortex slot can give you some decent wins. The max payout here is a nice 5,000x your stake.

RTP and Volatility

The Diamond Vortex slot boasts high volatility, which is a good sign if you’re after bigger wins. The RTP is 96.2% sitting just above the industry’s average mark.

Where to Play Diamond Vortex

There is no better place to play Play’n GO slots than at Play’n GO online casinos. But with the choice so big, you’ll want to narrow down the supply by checking who gives the best bonuses. Start by exploring the offerings on the esteemed Karamba or Leo Vegas casino sites for a fun or even free session on the slot.

Slot Name on Mobile

Playable on any Android and iOS device, the mobile version of the Diamond Vortex slot offers some smooth and mesmerising gameplay. Load up the slot via your favourite mobile casino that hosts the developer’s slot and have fun on the move.
