Big Win 777

Big Win 777 is an online slot by developers Play’n Go. Although it has a retro vibe with classic gameplay in the base game, there are a whole load of bonus features to keep things fresh and exciting.

When people talk about retro style slots, it often means the visuals have a deliberately outdated feel to recreate the style of early land-based and online slots. That is definitely not the case here.  

The design is sleek and modern, with the 5x3 gold-trimmed game grid set against a backdrop of disco lights sweeping across a dance floor and sparkling animations when you hit a win. 

The soundtrack is made up of catchy dance tunes that will have you tapping your toes as you watch the reels spin. Overall, despite the retro label, this is a sleek modern game with fantastic bonus features which can award prizes of up to 5,000 x the stake.

The betting range is from 0.15 to a max of 90.00, but the volatility is high, so you'll need to manage your bankroll well while trying to hit the bonus rounds where the big wins are to be had.

There's a distinct Las Vegas vibe to the game, and this is reflected in the symbols on the reels. There are seven of these in total, and they include a blue single bar, a red double bar, and a purple treble bar which act as the lower-paying symbols. A red double 7 and a gold triple 7 pay out higher amounts, and the most valuable symbol in the game is the Diamond Wild.  

Wins are formed by landing matching symbols on a payline from left to right, starting with the outside left reel. You’ll need at least three of all symbols except the Triple 777 and the Diamond Wild to form a win. The Triple 7 and Diamond symbol will give a payout for only two on a payline. 

The Diamond Wild not only helps create wins by substituting for other symbols, but it also gives a payout of its own if you land two or more on a payline. These payouts are as follows 1 x, 3.33 x, 16.67 x or 66.67 x your stake for 2, 3, 4 or 5 on a payline. 

Finally, there is a Chance Wheel logo as a Scatter. This can only land on reels 1, 3 and 5 and is key to triggering the Wheel of Fortune bonus round.

Play'n GO haven't spared any efforts when it comes to the visual design of this game. And the same can be said when it comes to bonuses. 

First, there's the Bonus Booster. This can trigger automatically at any time in the base game, and when it does, more Chance Wheel Scatters will land on the reels, boosting the player's chance of landing three across reels 1, 3 and 5. When this happens, the Chance Wheel bonus is activated. 

The Chance Wheel bonus takes place on a new screen where you'll see a Wheel of Fortune. This spins and awards cash prizes which range from 5 x your stake to the game's top prize of 777 x the bet. It can also give you access to the Big Win Free Spins round. 

Once the Big Win Free Spins feature is activated, you start out with 12 Free Spins. Landing 1, 2 Scatters during this bonus round will add 1 or 2 more free spins to your total. If you get three scatters, you'll get either 5, 10 or 20 additional free spins – and these can keep triggering as long as the Scatters keep landing. There are no limits except those imposed by luck. 

During Free Spins, all Diamond Wilds that land stick and duplicate themselves for the next two spins. This means that if you land five on one spin, you could cover the reels in wilds in the next two spins.

This Play’n GO retro online slot machine is one of the most exciting titles to date. Both retro lovers and those new to the genre will love the entire gaming experience, filled with engaging bonus features and generous payouts!
