Giga Zombies GigaBlox™ Slot RTP, Details & Wager Limits
The Giga Zombies GigaBlox™ slot game is played on a 6×5 game grid. Create winners by landing 8 or more matching symbols or wilds anywhere on the reels. When a winner hits, an avalanche follows. The successful symbols are blasted from the grid and replaced by new ones. The avalanches can bring extras into play, which I’ll look at in detail in the Bonus Features section below.
You can join this zombie hunt at stakes of between 20p and £100 per spin. There’s a quick spin mode if you want to up the pace. You can also set up to 1,000 autospins. Autoplay and quick spins aren’t available to UK players, though.
At most UK online casinos, the Giga Zombies GigaBlox™ RTP is 96%. That’s about average. Check out the top RTP slots in the UK for the best payout percentages. The hit rate is 35.08%, but overall, the volatility is high. The Giga Zombies GigaBlox™ max win is 6,260x. That’s a bit low compared to what’s on offer from the best new casino slots, but still decent enough.
As usual, I recommend playing the Giga Zombies GigaBlox™ demo slot first. It’s one of a superb collection of free slots to play for fun on our virtual shelves. I landed my biggest win testing this game during the free spins. That 212x payout was largely down to getting the multiplier moving.
Giga Zombies GigaBlox™ Theme—Enter a Post-Apocalyptic Jungle
When it comes to the best online casino slots for atmospheric sound and visuals, you can usually rely on Yggdrasil Gaming. The Giga Zombies GigaBlox™ slot is a typically immersive affair.
The ruins of a jungle pyramid form the backdrop to the reels. There you’ll find A to 10 royals spinning alongside a quartet of higher-paying zombie symbols. There are plenty of moving parts, but the colourful imagery makes everything easy to identify.
The guitar-heavy, rock soundtrack isn’t exactly an earworm but does deliver a brooding intensity that fits the theme nicely.
I like what Yggdrasil has done here. It’s just what we’ve come to expect from online slots from this developer.
Here’s what the paytable looks like:
| Symbol | Payouts/Info |
 10 | 8 to 15+ = 0.1 to 1.5x the stake |
 J | 8 to 15+ = 0.2 to 2x the stake |
 Q | 8 to 15+ = 0.25 to 2.5x the stake |
 K | 8 to 15+ = 0.4 to 5x the stake |
 A | 8 to 15+ = 0.5 to 6x the stake |
 Blue Zombie | 8 to 15+ = 0.75 to 7.5x the stake |
 Green Zombie | 8 to 15+ = 1 to 10x the stake |
 Purple Zombie | 8 to 15+ = 1.25 to 15x the stake |
 Orange Zombie | 8 to 15+ = 5 to 25x the stake |
 Wild | Substitutes for all symbols above |
 Scatter | 4, 5 or 6 = 1.5, 2.5 or 50x the stake plus 8 free spins |
Giga Zombies GigaBlox™ Mobile Slot
I enjoyed playing this slot at the mobile Giga Zombies GigaBlox™ casinos. The visuals are sharp, even if you’re playing on a smartphone. I found landscape mode delivered the best experience with the 6×5 game grid. If you’re playing the Giga Zombies GigaBlox™ slot at a mobile casino, it’s dead easy.
Giga Zombies GigaBlox™ Bonus Features
There’s a very solid collection of Giga Zombies GigaBlox™ bonus features. Avalanche wins can bring colossal symbols into play as well as free spins and massive multipliers. Let’s take a closer look.
Progress Bar
Each time an avalanche takes place, one point is added to the Progress Bar above the reels. Reach milestones on the Progress Bar to bring extras into play.
Collect 4 points, and a random GiggaBlox™ symbol is dropped onto the reels. This can be 2×2, 3×3 or even 4×4 symbols in size.
After six avalanche wins, between 1 and 4 wilds are added to the reels before the next avalanche.
After nine avalanche wins, you’ll trigger the free spins.
If you land a winless avalanche, the Progress Bar resets to zero.
Free Spins
Trigger the bonus round via the Progress Bar or by landing 4 or more Free Spin scatters on the same spin. You’ll then go on to play 8 free spins. One random GiggaBlox™ symbol is guaranteed to land on each free spin.
The Progress Bar changes during the free spins, too. Each avalanche win adds one point to the Progress Bar, boosting your chances of landing a big multiplier boost. The further you advance, the bigger the multiplier. These multipliers start at 2x but can reach 50x. The multiplier is applied to the win at the end of each avalanche, then reset. If you manage to get 9 avalanches, you’ll land a re-trigger and another round of 8 free spins.
Random Modifiers
Giga Zombies GigaBlox™ also comes with a trio of randomly triggered modifiers that can land on any winless spin.
- Zombie Horde! – Unsuccessful symbols transform into high-value symbols and a winning combination.
- Chaos Kingdom! – Random symbols are transformed into a new winning combination.
- Lucky GigaBlox! – A random 2×2 set of symbols is upgraded into a GigaBlox symbol, and a new winner is created.
Bonus Buy (Not Available to Players in the UK)
If you’re in a territory where it’s allowed, you can buy the Free Spins feature for a fee of 100x the stake. This isn’t available if you’re in the UK, though.
Giga Zombies GigaBlox™ Verdict: This Entertaining Slot is No Horror Show!
With features galore, there’s plenty to enjoy in this cartoonish zombie hunt.
I’m not a huge fan of zombie movies, but I found these slot zombies more to my liking. The avalanche game mechanic delivers plenty of action, especially if you manage to trigger the free spins. The extra GigaBlox and the potential from the multipliers make for a potent combination. This is a high-variance slot, so tread carefully.
The design is as accomplished as you’d hope from a release from the Yggdrasil stable. The stats are solid without being spectacular.
If you like cartoon horror, there’s plenty to like about Giga Zombies GigaBlox™.
