Hades Gigablox RTP and Wagering

Hades Gigablox - RTP and Wagering

Hades Gigablox features an unusually square setup consisting of 6 reels and 6 rows. This allows for a total of 50 paylines formed by landing 3 or more matching symbols on adjacent reels. Paylines always start from the leftmost reel, moving from the left to right, while big “block” symbols count as multiples according to their size (so a 2x2 block counts as 2 symbols, 3x3 as 3 symbols, and so on). 

The RTP of Hades Gigablox is set at 96%, which in a way is the ideal as far as slot games go. The volatility feels pretty high from our testing, while wins can reach up to 11,129x the stake. Betting starts from as low as £0.10, and you can set your stake by adjusting the coin value using the controls found underneath the reels.

Hades Gigablox Symbols and Audio & Video Design

Yggdrasil has truly put its all in the visuals of Hades Gigablox. Check out the foggy underworld setting, or the columns carved with skulls and serpents bordering the reels. Look at the animated Hades on the right-hand side of the reels, clad in a cloak of what appears to be smoky darkness. He can even come to life on random spins to hunt down monster symbols on the reels, further adding to the excitement of your gameplay session. 

We’ve already mentioned how symbols can land in big block form up to 6x6 in size, but we haven’t told you what they actually are. There are 8 paying symbols, 4 of which are high-paying monsters and the 4 card suit low pays. Wilds can substitute for all paying symbols, but these only appear on the reels through the Hades Wild Hunt feature. Last but not least is the free spins scatter. You need to land 5 or more of these to trigger the free spins. Scatters can land in big block form, with the number of scatters based on the size. Thus 2x2 scatters count as 4 scatters, 3x3 as 9 scatters, and so on. 

Let’s see how much symbols are worth:

Hades Gigablox Mobile Features

Hades Gigablox might be a big slot but it is still perfectly playable on small screen devices. This is thanks to HTML5, the technology that allows developers like Yggdrasil to build games that are not only playable on internet browsers, but can adjust automatically to fit the size of the device in question. You can even play Hades Gigablox on your smartphone in portrait mode and the game will set the UI and visuals for the optimal experience.

Hades Gigablox Bonus Features

There are a couple of bonus features of note in Hades Gigablox. The Hades Wild Hunt is a randomly triggered feature, while free spins can be obtained by landing scatters. Let’s take a closer look at both of these. 

Hades Wild Hunt 

Any random see might see Hades decide to hunt down the monsters on the reels. This turns those monster symbols into wilds which can substitute for all symbols except the scatters.

Free Spins

Landing at least 5 scatters triggers the free spins, with the number of spins being equal to the number of triggering scatters. As explained earlier scatters in big block form count as multiple scatters according to their size. Landing a scatter during the free spins adds +1 spin to the total. 

The Wild Hunt feature is activated on each free spin. Each successful hunt adds +1 point to the multiplier counter, with the number of points based on the size of the monster symbol. For instance, a 2x2 monster block equals 4 points. In addition, reaching a higher multiplier level adds +2 free spins. The multiplier system works as follows:

Hades Gigablox Final Thoughts

Hades Gigablox represents some of the best Yggdrasil has to offer as far as slots are concerned. The core mechanic is rock solid, with the high volatility leading to exciting spins with big win potential, while the randomly triggered Wild Hunt adds that extra bit of spice. It does take a while to get the free spins, but once you do these are packed with action through the multipliers activated through the Wild Hunt. In conclusion? Hades Gigablox is a must play, and as such comes highly recommended.
