Big Win 777 slot review

Play’n Go may be known for their iconic themed slots, but we at JohnSlots really feel they’ve hit the mark with Big Win 777. It’s simple, it’s fun, it’s nice to look at – and most importantly, it’s thrilling. This Vegas-style slot comes complete with a Chance Wheel which, if you get the opportunity to spin, can award some generous extra prizes.

If you love a highly volatile classic slot with the addition of extra features, Big Win 777 is definitely one to try – and we’ll go through why now in our review.

Big Win 777 slot by Play'n Go

Big Win 777 bonus features

The features of Big Win 777 may be simple, but they’re enough to conjure up images of Vegas – particularly with the addition of the Chance Wheel. You’ll also find more features in Big Win 777 than your typical classic slot, making it much more exciting. We actually preferred to play this slot without autoplay since there’s more than enough going on to keep you occupied.

We’ll go through each of the features below to give you a handy guide of what to look out for.

Free spins

The free spins round is probably the one you’ll want to hit the most since here you’ve got the opportunity to land the maximum win. This feature can be triggered in two ways:

  • Booster Spin feature
  • Chance Wheel

With either option, you’ll be given 12 free spins to start with – but these can be retriggered by landing scatter symbols on the reels during the round. One or two scatters will award an extra one or two spins respectively, but three or more scatters will randomly award either five, 10 or 20 extra spins.

Additionally, if a diamond wild symbol lands on the reels, it will hold in place as the reels respin twice in search of more prizes. A win that includes a diamond wild can award up to 1,000x your stake, and if this happens with five diamond wilds, you’ll hit the maximum win of 5,000x.

Booster Spin feature

This feature is triggered randomly in the base game, and increases the odds of landing higher paying symbols, but more importantly free spin symbols.

Chance Wheel

The Chance Wheel is really what gives Big Win 777 its Vegas feel, and it’s triggered by landing three Chance Wheel symbols across reels one, three and five.

You’ll then see the big colourful wheel appear, which has prizes of free spins and cash prizes from 5x to 777x your stake. That nice big prize of 777x is obviously quite good to hit, but we were always hoping to land on free spins since this is the true moneymaker of the game.


The diamond wild symbol can substitute for others to complete your paylines (except for the Chance Wheel symbols), and it will also “clone” symbols above or below it to expand and give you more chances of winning.

Big Win 777 jackpot

The only thing that could give this slot even more of a Vegas feel would be a jackpot – but unfortunately, it wasn’t included in this game. The 5,000x prizes are definitely pretty thrilling though, so there are still some hefty prizes to be won.

RTP and volatility

Big Win 777 is a highly volatile slot and you might find that there are fewer of them between spins. That kind of comes with the Vegas-style territory though, since when the wins do land, you’ll be excited about it. The return to player is also nicely on the higher-than-average side, sitting at 96.5%.

Big Win 777 on mobile

You’ll be able to play Big Win 777 across almost any device you please, but at JohnSlots we particularly enjoyed playing on mobile. It really seems to have been optimised for the smaller screen.

What does John have to say?


Forget branded slots and intricate themes - I love nothing more than a Vegas-style slot! The features, graphics and gameplay makes Big Win 777 one of my favourite Play’n Go slots by far.
