Nightmares vs Gigablox Slot Game Free Demo

Facing up against the creatures of the night comes with its fair share of challenges and you’ll need all the practice you can get. That’s why you should try out the Nightmares vs Gigablox slot free demo before playing for real money. Of course, the slot runs on a completely randomised algorithm, so there are no strategies to learn here, but the demo helps you familiarise yourself with the game’s symbols, features and drop rate. It’s ideal to understand what ideal bet levels you should set to suit your gaming budget.

Pro Tips:

Despite its medium to high level of volatility, I struggled to trigger Nightmares vs Gigablox’s bonus game. Sure, I landed quite a few base game wins along the way, with no shortage of wins hitting through the Gigablox symbols, but the best wins ultimately came from the versus feature. I got my first trigger after 120 spins, although consecutive activations didn’t take all that long to drop. My success here mostly depended on how far I managed to make it up the bonus trail, with loads of win multipliers and additional free spins helping along the way. Make sure you pick a bet level you can afford in the long run, giving you plenty of opportunities to trigger and retrigger the bonus mode.

Nightmares vs Gigablox Slot Bonus Features

The derelict roads of Nightmare vs Gigablox’s setting are teeming with all kinds of vicious creatures, sent back to earth from the very bowels of hell to rain terror and Gigablox payouts on unwilling players. But when it comes down to it, this is yet another entry into Hot Rise Games’ ever-popular ‘Versus Gigablox’ series.

Not much has changed here. You get the same features you fell in love with over the first two games, minus the free spins bonus. That’s right! Nightmares vs Gigablox does away with the traditional special bonus, so you simply switch between base game spins and the coveted Versus feature.


You’ll need all the help you can get when facing the denizens of darkness, and wild symbols can give you just the boost you need. They pop up as golden crowns, stepping in for missing pay symbols that can form a winning payline. Wild symbols pop up quite often and saved me a good deal of grief, both in completing paylines on near misses and enhancing existing wins.

They also have their values, which are equal to those of the Vamptress, which offers 500x your stake for five of a kind. They’re also incredibly helpful when landing next to Gigablox symbols.

Gigablox Symbols

The titular Gigablox makes yet another appearance, landing mega symbols across the reels that can cover spaces anywhere between 2×2 and 6×6. The Gigablox stacks can lead to some massive wins since each tile in the Gigablox counts as an individual symbol.

Think of them as massive symbols stacks that can help you hit the five of a kind of any symbol in the game. Of course, you’ll need to have them form part of a win to get that sweet payout.

Scatter symbol

Base game spins and Gigablox can be eventful enough, but ultimately, you’ll want to get to the special Versus feature to land the game’s biggest wins. That’s easier said than done since you’ll need no less than six scatter symbols to make it to the bonus game.

The game’s medium to high volatility means it’s not all that hard to put these together. But I must admit that I did struggle to land my first trigger, which took well over 150 regular spins. I managed to activate the bonus a couple of times after that and even dipped into the bonus buy feature a couple of times.

The bonus buy feature costs 80x your stake and guarantees six scatter symbols to unlock the Versus feature.

Versus Feature

This is the main event of Nightmare vs Gigablox and it follows the same fighting game structure that the series is known for. At the start of the bonus rounds, two nightmare characters are randomly selected from the roster, facing each other on opposite sides of the reels.

You start with six free spins, during which symbols that correspond to the two chosen characters are collected. They’re added to the character’s bonus trail and can unlock win multipliers, additional free spins, wilds and major prizes. The major prizes give you massive win multipliers that can help you hit that 7,353x max win.

It’s a particularly exciting bonus that had me at the edge of my seat throughout. But it is ultimately a rehash of the previous versus features, with no significant overhauls to push the mechanic further.

RTP & Volatility of Nightmares vs Gigablox Slot

Nightmares vs Gigablox sets a medium to high level of volatility. It means wins and special features aren’t all that rare, even if they don’t land on every other spin. But Hot Rise Games makes up for it with a relatively low RTP setting of 96.1%. It makes for a rather balanced math model, although you can find other versions out there with lower RTP rates of 93.9%, 90.6% and 86.4%.

Rest assured that Nightmares vs Gigablox is a very safe game to play. It’s developed by Hot Rise Games in conjunction with ReelPlay and Yggdrasil Gaming, which are all trusted game providers in the online casino industry. Of course, I urge you to play at a licensed online casino to ensure your overall safety.

Nightmares vs Gigablox Slot on Mobile

Feel like taking your nightmare creatures for a walk? Well, you can play Nightmares vs Gigablox wherever you like thanks to the game’s fantastic mobile compatibility. The mobile version is compatible with both Android and iOS devices and responsively adapts the interface to fit on smaller screens while automatically adding touchscreen controls. So, you get the full experience regardless of the device you’re playing on, complete with all the same great graphics, versus features and maximum payout you get on the desktop version.


If you’re up for a spooky slot where deadly creatures battle it out over rewarding win multipliers, then you’ll want to check out Nightmares vs Gigablox. The game maintains the same momentum set by its predecessors with both the Gigablox symbols and the Versus feature providing loads of entertaining spins and fantastic wins.

But at the same time, I feel like the formula is beginning to show its age. Whereas Gods vs Gigablox is built on the promise of the original game, Nightmares vs Gigablox stagnates. It removes the free spins feature and doesn’t add anything new. Sure, the gameplay loop is fun enough, but unless it continues to invest in the winning formula with bigger and better mechanics, the whole ‘Versus Gigablox’ series might run out of steam quickly.

I ultimately had a great time playing Nightmares vs Gigablox and if you’re up for another spin on the series with a handful of Halloween characters to keep you company, then be sure to give it a go too!


That’s all for the Nightmares vs Gigablox review! But if you still have more questions to ask about these garish creatures and the rewards they offer, be sure to drop me a message from the contact form below. I’ll get back in touch as soon as these undead monstrosities are safely back in the ground! And have a loo

To progress in the Versus feature’s bonus trail, you’ll need to land symbols that correspond to the two characters that get chosen at the beginning of the bonus game. The more symbols you collect, the higher up the ladder you’ll go and the better the rewards you’ll unlock.

Yes, all symbols including wilds and scatter symbols can land as Gigablox in Nightmares vs Gigablox.

The bonus buy feature costs 80x your stake and awards you with an immediate six scatter symbols. This takes you directly to the Versus feature.

The free spins bonus that came with previous ‘Versus Gigablox’ games has been removed. But you still get the Versus feature as a bonus game.
