Nightmares Vs Gigablox Slot Review
The theme of this new Reelplay slot may be all about nightmares, but there are some absolute dreamy bonus features, from the special Gigablox function to the Versus feature, which pits two symbols against each other. All of this leads to a far from nightmarish total win of 7353x.
Do You Dare Go to Sleep?
Forget the usual nightmares (taking your physics GCSE with no preparation, or turning up to work naked), the bad dreams Reelplay have chosen to focus on here are characters from classic horror films. Among the rest, you’ll find a wolf man, a swamp monster, a mummy and lots more creatures of the night!
Nightmares Can Come True
As you would expect from a Reelplay video slot, the graphics here are very well done. It’s set in a spooky village in the mountains, complete with beamed houses and a hazy background. Just the sort of spot where you’d expect to find a mummy or a wolf man or any other of the characters featured here.

How to Win at Nightmares Vs Gigablox

The Gigablox feature was originally developed by slot makers Yggdrasil but has been utilised in partner games, such as this one from Reelplay.
Top Symbols
The winning symbols in Nightmares Vs Gigablox are split between high-paying characters, such as the mummy Princess Cleo, Dead Beard the pirate and Max Wolf, and lower-paying playing cards. The smallest wins come from the J-A with a max win of 1.5x. The top payout potential comes from the characters, who offer a top win of 10x. The best wins, though, come courtesy of the wild.
Betting Limits
Bets in the Nightmares Vs Gigablox slot start at 0.5.
Nightmares Vs Gigablox Bonus Features
If you’re a regular slots player, then you may have already sampled the Gigablox feature in the previous two incarnations. It appears again here, alongside another bonus you might have seen elsewhere: the Versus feature. All of these combine to create a varied playing experience.
Gigablox Feature
The Gigablox feature can kick in randomly throughout the base game. When it does, symbols will merge to become a giant block that covers an area between 2x2 and 6x6 on the grid, helping you to score more potential wins.
Versus Feature
The Versus feature is activated when you land six or more of the game’s scatter symbol in the base game. Once triggered, the game will pick a Champion and a Challenger character from the high-paying symbols (for example, Princess Cleo versus Dead Beard) to compete against each other. You’ll then be given six initial free spins. As the round progresses, your Challenger and Champion can build up towards specific rewards, which include:
- 5 symbols collected - x2 win multiplier,
- 10 symbols - the Champion symbol becomes wild, or the Challenger receives a x5 win multiplier,
- 30 symbols - 3 free spins for the Champion or 2 for the Challenger,
This can go up to 100 symbols, which will deliver a major prize to both the Challenger and the Champion.
