How to Play 777 Surge

777 Surge Bonus Features
Just as a casino welcome bonus might tempt you to play at a particular casino, the bonus features offered by this online slot might draw you into giving 777 Surge a try. To tempt you a little more, here’s some details about the bonuses on offer.
Mini Reel Bonus
Land at least 3 of the bonus symbols and you will launch the game’s Mini Reel Bonus. Each of the bonus symbols will then become a little mini game, with 3 reels, 3 rows, and a payline. Each of the bonus mini reels will spin once to see if they can give your prize pot a boost.
Land three of the 777 icons during the Mini Reel Bonus to land that reel’s top prize, which is displayed at the top. £ orange 7s can pay up to 80,000, following by pink 7s with a 4,000 prize, and blue 7s delivering a 2,000 win.
Free Spins Scatter
The Free Spins scatter symbols can land on the central 3 reels and a trio of the icons will start the slot’s free spins wheel feature. Three of the scatters also pay out 1x your total bet.
If you launch the free spins wheel, you will spin a free spins wheel and a multiplier wheel to decode how many free spins you get and what multiplier will be applied to any wins that arrive. The maximum is 30 free spins and a 5x multiplier.
The slot also has a wild symbol, which can replace any icon except for the Free Spins scatter icons and the bonus symbols. It also offers wins for matching 3 to 5-of-a-kind. You could win up to 1,200 for matching all 5.
777 Surge Review
This slot review has to start by talking about the original nature of this game. It can feel like game after game are created using just a few formats but this one breaks the mould and really does offer something different. The features are cool and fresh and there is no shortage of winning potential on offer. Don’t be fooled by the classic theme, this game is much more forward-looking than you might think.
