777 Volt GigaBlox is an electrifying slot by Yggdrasil Gaming. As is often the case with this famous developer, the slot hides many surprises. A medium volatile bonanza, it has up to seven random features in the free spins round, so it’s time to buckle up and join the ride.
The slot has a 6x4 setup and a varying number of paylines — from 25 to 40. Not like in Megaways titles, but rather standard paylines where symbols can land to provide a payout. The math model states that you need three or more identical symbols per line and up to six to hit a win. A wild symbol substitutes for others in winning combinations while offering its own payout.
The slot’s main highlight are the GigaBlox symbols. Just like in other slots bearing the same name, at least one of these huge symbols is guaranteed to land per spin. Their sizes vary – some are 2x2, others are 3x3 or up to 6x6 in the bonus round. It’s safe to say they offer enormous winning potential and are the key to unlocking the higher wins.
If this sparks your interest, read my 777 Volt GigaBlox review for detailed information on the game and its features.
777 Volt GigaBlox has quite a minimalistic approach when it comes to layout and design. The background is a two-tone animated façade with the grid slapped on top. All the controls, including the paytable and guide, are on the right side for easy access. The great visuals and animations are paired with upbeat audio that picks up as you hit win after win.
Like other Yggdrasil releases, the graphics and animations are as sharp as possible. This is a mix of vintage slot and modern slot mechanics, which honors both sides of the slot coin. Regarding symbols, you get plenty of old-school items, including single, double, and triple 7s in different colors, gold bars, and a big diamond, too.
777 Volt GigaBlox was just the kind of refreshing experience I needed. It looks and feels like a classic slot but with many modern features. I have to say that the base game was more than rewarding. Thanks to the medium volatility, I regularly hit decent wins over 10x during my playthrough and review.
Playing the 777 Volt GigaBlox slot in online casinos is easy. You start by setting your bet between 25c and $100 per spin. After you’ve chosen your bet size, click SPIN or use the autoplay feature for up to 100 automatic spins. You need three to six matching symbols to hit a winning combination. The wild can help complete combinations while also paying on its own.
The main highlight of this slot (as the name suggests) is the GigaBlox feature. More specifically, the GigaBlox symbols, which can reach massive sizes of up to 4x4 in the base game. At least two adjacent reels connect to create these huge GigaBlox symbols.
A diamond can also land on the grid in all game stages, but only on the 5th reel. It can land partially or fully on the reels, awarding cash prizes up to 2,500x in the base game or extra spins in the bonus round. The larger the diamond, the better your opportunities at hitting larger prizes.
Thanks to the gigantic symbols, hitting wins in the base game is much easier. The larger the symbols, the higher the number of paylines and winning opportunities. However, the big highlight in this electrifying slot is the bonus round, which comes with eight random features.
Landing five bonus symbols in the base game will provide five free spins. Right before the start of the bonus, you’ll be assigned several picks that give you 3-7 random features for the free spins round. Use your picks to find the most exciting features to boost your bonus wins. Also available before the bonus round begins, you can gamble for more features and get all the way up to eight.
The features include:
All the active features will stay in play for the duration of the bonus round. Since this is also one of the slots with bonus buy, it allows you to buy the bonus for a price that depends on your bet. You can buy 5-16 free spins with 3-7 or 4-8 features.

The bonus round wouldn’t give after a while, so I decided to buy the cheaper option with three features. The modifiers did the job pretty well. I ended up with a 75x return during my session, which justified buying the bonus round.
777 Volt GigaBlox has an RTP of 94.00% with medium volatility. The maximum projected win is 5,000x the bet.
Yggdrasil strikes a hit once again with 777 Volt GigaBlox. It’s a decent slot with great features, including the bonus round modifiers that can pay a ton. The slot’s fun gameplay and the GigaBlox symbols make it more than worth your while, so if I were in your place, I’d give it a few spins.
If you like the GigaBlox mechanic, you can try other games that feature it. Those include Yggdrasil’s Primal Hunter GigaBlox and Tiki Runner GigaBlox. However, if you're up for a different experience, you can try the studio’s hit Valley of the Gods or its sequel, Valley of the Gods 2.
