Description of the Slot 

Fruit slots might appear to be things of the past, but they are still pretty popular among players. Since slot gambling had a humble beginning with fruit games, many players identify a fruit theme as an actual representation of casino games. To keep this tradition alive, Microgaming and Gameburger Studios came out with 777 Surge in April 2022. 

777 Surge is a blend of a traditional fruit machine and a modern video slot. The game unfolds on a 5×3 grid layout and 20 fixed paylines. The most eye-catching part about the slot is its mini reel bonus game, where each bonus symbol acts like a classic 3×1 fruit slot. Besides this, you also get a free spins bonus game with multipliers. So, without waiting any further, let’s find out all about this tweaked fruit machine. 

Design and Audio 

The slot has a vibrant design with red, pink, orange and purple colors aligning with one another. 777 Surge’s grid looks like a retro arcade machine dabbed completely in purple. A closer look into the game’s symbols confirms it’s a fruit slot, although with a landslide majority of Lucky 7 symbols. Behind the reels, a free spins wheel keeps spinning and comes to the front if you trigger the bonus feature. 

The background score also feels nostalgic and sounds like you are playing a Nintendo game from the 90s. But as soon as the reels start spinning, the music’s tempo leaps and turns into a piece of pacy Jazz music. 


777 Surge has two special bonus features, both capable of drawing in impressive returns. 

Mini Reel Bonus 

Hit at least 3 bonus symbols in the base game to activate the Mini Reel Bonus game. The bonus symbol appears in the form of a mini 3×1 reel set with a single payline and it spins separately during the bonus game. When the mini reel spins, different winning combinations are possible. The highest win occurs when 3 orange Triple 7 symbols land in a mini reel. A paytable shows next to each mini reel to give you a quick summary of the payouts. 

Free Spins 

The free spins logo is the slot’s scatter symbol and appears only on the three middle reels. Landing 3 scatters in a spin triggers the Free Spins Wheel Feature. A special wheel appears before the main feature begins. At first, the free spins wheel reveals how many free spins you have won. Following that, a multiplier wheel rotates to determine the multiplier that’ll apply to your wins. 

During the free spins wheel feature, you can win 7 to 30 free spins and 2x to 5x multipliers. Landing 3 additional scatters during the bonus round awards the retrigger with the exact number of free spins and multiplier you won initially. 


777 Surge is replete with lucky 7 symbols. Apart from the mini reel paytable, a standard collection of symbols can lead you to wins during the base game and free spins. Among these are cherry, BAR, bell, dollar, single, double and triple 7s, offering 1x to 30x the bet for landing five matched ones on a payline

The paytable also includes wilds that substitute for all symbols except the mini reel bonus and free spins scatter symbols. If you step into the mini reel bonus game, you can win up to 2000x the stake. However, the slot’s max win potential stands at 6000x the stake. 


777 Surge fulfills your craving for retro slots by blending modern features into the game. Technically, it’s a fruit slot, but here you’ll find the paytable stacked with variations of lucky 7 symbols. Since Lucky 7 is usually a premium symbol in online fruit slots, 777 Surge emphasizes this particular symbol. 


An impressive set of payout features directly impacts the volatility levels. 777 Surges comes with a high volatility math model suggesting a streak of winless runs before something major drops.

Final Considerations 

777 Surge is an interesting take on retro fruit gaming. The slot keeps the old-school vibes without looking outdated. Incorporating several exciting features in the game surely spices things up for players who like to enjoy the best of both worlds. But what’s even more impressive about the slot is its powerful math model. Apart from high variance and impressive payouts, the slot also boasts a splendid RTP of 96.44%
