777 Surge from Gameburger – a partner of experienced slot developers Microgaming – takes things back to basics with a classic slot layout and design. It’s a slot of reasonably high volatility, and comes with a pretty standard RTP rate of 96.44%, but we’ve found that the bonuses are triggered with surprising frequency for a volatile slot.

However, with that said, we would still maintain that this is a slot best suited for high rollers, as you might have to wait some time before you earn yourself a genuinely lucrative payout. If you want to maximise your enjoyment of this game, bet with low stakes and enjoy all the colourful graphics and exciting bonus features. Read on to find out more about what makes 777 Surge great!


  • Classic slot design
  • Fun bonus features, such as Mini-Reels
  • Maximum payout at 6000x
  • Fun presentation, with stimulating graphics and music


  • High volatility means 777 Surge better suited to high rollers
  • Moderate RTP rate of 96.44%


Gameplay, RTP, and Variance


777 Surge goes back to basics in terms of gameplay with a classic 5 x 3 reel layout. With an average RTP rate of 96.44% and high volatility, it can be quite hard to land winning combinations on 777 Surge. However, when they do come, 777 Surge often reward players for their patience with substantial payouts, but this dynamic still means that the game is more suited to high rolling players that are perhaps more comfortable with losing money before they make any back. Those who like to play with small budgets might often find that they are having to wait too long for a valuable payout, which can cause frustration.

But, such is the nature of classic slots like this, which are designed to look like land-based slot machines that are traditionally more volatile than your average online casino slot. As a result, the high volatility of this game is an integral part of its overall gameplay, functioning much like a physical, traditional slot machine.

Bonus Features


There are two primary bonus features in Gameburger’s 777 Surge. One is the free spins bonus round that occurs whenever you land three scatter symbols – which are, helpfully, symbols with the words ‘Free Spins’ on them – triggering a bonus wheel that spins to reveal a number of free spins with a specified multiplier.

The other main bonus feature is the Mini Reels function, which is, according to Gameburger themselves, ‘a modern interpretation of an extremely popular classic land based feature’. This occurs whenever you land three bonus symbols anywhere on the reels, triggering a 3-reel mini game for each bonus symbol that can result in huge jackpots. This explosion of activity, which isn’t as infrequent as you might expect from a highly volatile title, is terribly exciting and satisfying whenever it occurs.

Mobile and Tablet Experience


777 Surge has been built with mobile users in mind. HTML5 technology means that it is optimised for use across desktop, mobile and tablet devices. Those playing on their mobile phone might notice a slight drop in performance due to the sheer explosiveness of the graphics, but our experience when testing it out on our iPhone 11 was smooth and highly enjoyable. If you haven’t played the desktop version, we’re sure you won’t even notice the slightly slower performance.

Design, Graphics, and Sound


777 Surge, as its name suggests, is all about energy. It features some extremely vibrant, colourful graphics and an energetic soundtrack. Though these may be a bit too much for some players, this presentation stays true to the real slot machines of Las Vegas, with the familiar sound of gushing coins whenever you land a win.

The only thing we can come up with by way of a criticism is that all of the combined design features might allow players to get a bit carried away, forgetting to keep an eye on how much they’re spending. So just make sure to remember that there is money on the line, but keeping your stakes nice and low should allow you to enjoy yourself without having to think too much about winning and losing.



We think 777 Surge is a fantastic modern interpretation of classic slot themes and bonuses. It’s a title that reminds its players that slots should be fun and enjoyable, while also offering ample opportunity for players to achieve some decent payouts. We do think that perhaps the game could be slightly less volatile, but this isn’t a big problem if you’re staying close to the minimum bets. Also, the Mini Reels feature – our favourite aspect of the slot – occurs with surprising regularity, often resulting in nice cash rewards.
