777 Volt GigaBlox RTP, Details & Wager Limits
Reels/Paylines: 6 reels + 25 to 40
paylines
Stakes Range: 25p to £100
Max Win:5,000x
RTP: 94%
Yggdrasil utilises its innovative GigaBlox mechanics on this release to make the gameplay more dynamic. The 777 Volt GigaBlox slot game has 6 reels, 4 rows and 25 paylines by default. During the bonus round, the grid can extend to 6 rows with 40 paylines.
When GigaBlox symbols appear, they merge the reels, starting from 2×2 and can grow up to 4×4 in the base game. Winning combinations are created by landing 3 to 6 matching symbols on the reels from left to right.
The minimum amount you can stake per spin is 25p, while the maximum is £100. It does not feature the “+” and “-” buttons, so you must select from a range of stake amounts.
To make the game run faster, initiate the Autoplay feature, which offers up to 1000 autospins, and set the stop options. However, this feature is not available in casino slots online in the UK.
777 Volt GigaBlox RTP is 94%, which lower than the standard average for online slots. Even more disappointing is a 90.5% RTP variant across UK online casinos.
The provider sets the volatility to medium-high, balancing large payouts and higher win frequency. This is an improvement from the high volatility trend in its previous GigaBlox releases.
The maximum win is 5,000x the bet. Your best shot at hitting this payout is by triggering the Diamond feature, which awards 500x bet twice and 16 free spins.
Theme: Step into the electrifying world
Theme: Voltage
High-Value Symbol: Horse
Compatibility: Mobile, Tablet, Desktop
Rather than adopting a colourful scheme like in 7 Gold GigaBlox, Yggdrasil takes a minimalistic and retro approach to this slot’s visuals. Nonetheless, the graphics and animations are sharp and capture the voltage theme perfectly.
The grid is set on a purple ombré background with twinkling tiny squares. Placing the controls at the right side of the grid -on desktop screens- rather than at the bottom is quite thoughtful, allowing users to maintain a laser focus.
The game lightens up as different colourful symbols appear on winning paylines as GigaBlox, subsequently expanding the reels and triggering bonus features. This, paired with the tecno-type of audio and cheerful sound effects, makes the game more thrilling.
On 777 Volt GigaBlox reels, you will find a blend of modern and vintage symbols. During the base game, 12 paying symbols, plus the wilds and scatters, can randomly appear on the reels. Playing cards represent the low-paying symbols, while the single, double, and triple 7s have the highest pay.
The wild symbol substitutes for other symbols and ranks as a paying symbol. Other symbols that can appear on the reels include gold bars, blue diamonds, and keys.

As a reputable provider in the online gambling industry, you can trust Yggdrasil to develop games compatible with all devices. As such, the 777 Volt GigaBlox mobile slot works smoothly on Android and iOS devices without distorting the graphics or overall gameplay.
Although the mobile casino version provides better convenience, big screens offer a more immersive experience.
777 Volt GigaBlox Bonus Features
The high-voltage slot has promising bonus features that boost your chances of hitting a high payout. Look out for the GigaBlox symbols and the Diamond feature, as they pay more than the rest.
Free Spins
Triggering the free spins feature requires hitting 5 or more scatter symbols on the reels during the base game. The number of free spins awarded depends on the number of scatter symbols that activate the feature.
Before the bonus round starts, you will be awarded 3-7 features that remain active throughout the session. One of the highlights of the game comes during the free spins. Two additional rows are added to the reels, expanding the grid to 6×6.
Here is a breakdown of the free spins features:
- Wild High: transforms 1 high symbol into a wild.
- X2 Multiplier: awards a 2x multiplier on all wins.
- Expanded Reels: adds two rows to the grid, offering more paylines and 6×6 GigaBlox.
- Extra Wild: adds 1-2 wild symbols on the reels during each free spin.
- High Stacks: transforms 1 high symbol into a super stacked symbol.
- Extra Free Spins: awards 1-5 extra free spins.
Before the bonus round starts, you can gamble for up to 8 additional bonus features using the free spins gamble feature. Guess which 2 of the 3 locked boxes hold a key to activate the feature. However, you will lose the existing free spin if your choice is wrong.
GigaBlox
GigaBlox are gigantic symbols that help towards huge payouts. These symbols can start randomly at 2×2 to 4×4 during the base game and expand to 6×6 in the bonus round.
The GigaBlox symbols act like individual symbols when they appear on the reels. For example, a 3×3 symbol covers 9 spaces and acts like 9 individual symbols on a winning pay line.
The wild, diamond, and scatter symbols can appear as GigaBlox symbols and at least one is guaranteed to land on each spin.
Diamond Feature
This feature becomes active by landing the diamond symbol on the last reel during the base game and bonus rounds. You can trigger a 2-500x bet in the base game, 5, 9, or 16 free spins. Similarly, the feature awards a 2-500x bet, 1, 2, 3, or 5 additional free spins during the bonus round.
The diamond symbol pays higher than others when it lands as a GigaBlox.
Golden Bet
After triggering free spins, you can activate the Golden bet to add 1 extra special feature to the reels. However, it costs 0.2x (20%) per spin.
Buy Free Spins
The Buy Free Spins feature lets you move into the bonus round directly from the base game. You can pay x60 to buy free spins with your choice of bet size or x100 to get an extra feature in addition to free spins.
Here is a breakdown of the offer:
- x60 Buy Free Spins: 5-16 free spins and 3-7 feature picks without the extra feature.
- x100 Buy Free Spins: 5-16 free spins and 4-8 feature picks with the extra feature.
Verdict: Energetic gameplay with multiple bonus features but retro visuals
777 Volt GigaBlox seamlessly blends a classic feel with new-age excitement. Every spin offers a unique thrill and great chances of unlocking innovative features. The gameplay is centered around the GigaBlox feature, which expands the grid from 2×2 to 4×4 and can reach 6×6 in the bonus round.
With the dynamic reels and medium-high volatility, I consistently landed winning combinations after a couple of spins. The payouts were often low, averaging below x6. Even so, I recorded occasional high wins, with a payout of 15x the most notable.
If the GigaBlox mechanic thrills you, you can try other top slot sites with the same feature. Some of the most popular are 7 Gold GigaBlox by 4ThePlayer and Water Blox GigaBlox by Peter and Sons.
A significant drawback of the voltage-themed slot game is its 94% RTP, which is lower than the standard average at UK mobile casinos. Overall, the 777 Volt GigaBlox slot game is an entertaining online slot game with bonus features that can provide chances to hit the 5,000x max win. I recommend playing the 777 Volt GigaBlox demo game for a more comprehensive experience. If you want to try some other free slots to play for fun, you can do so on Online-slots.co.uk.
