Big X Features

With a traditional fruit machine setup, you wouldn’t normally expect a load of clever features; that would go against the grain of such a classic game. But we do want something to get our teeth into and SYNOT Games has duly obliged.

With this game, you’re treated to 2 bonus features—which have pretty similar outcomes it has to be said—but they can both potentially add some nice wins to your balance so we can’t really complain! There’s also a smart little multiplier modifier added to some parts of the win lines that can help send your bankroll in the right direction.

Mystery Symbols

Everybody loves a mystery prize; even more so when that prize can be up to 50x! To land this top win, you'll need 3 Mystery Symbols to land anywhere on the screen and as a result, the good times really start to roll. You'll see the multiplier board to the left of the reels come to life and you simply need to wait for the lights to stop on your chosen prize.

Big X

If you like the sound of the mystery prize outcome, then you are going to love Big X. It all begins with that strange X overlay on the middle of the reels and to make this spring into action, an ‘X’ symbol needs to land in that spot.

This feature is a re-spin bonus but not in the way that many producers are choosing to present them these days. You don't get 3 re-spins that are replenished, instead, ‘X’ symbols spin around and hopefully stick on the reels. 

If one lands, then you get another re-spin but if you don't find one, then it's game over. At the end of the feature, you are awarded a multiplier prize in a very similar manner to the Mystery Symbol feature. 

However, this time, all of the ‘X’ symbols in view will receive the same prize. A full set of them will also add a further 50x to your win total.

Multiplying lines

This is a very simple modifier that could have fantastic consequences for your balance. Quite simply put, wins on paylines 4 and 5 receive an x2 multiplier. Why? Why not, that's what we say!

Big X Review

When players hit the spin button on a slot like this, they want a familiar feel, those old recognisable sounds and a chance to hit a decent win without ridiculously high volatility. That's exactly what you'll get with Big X.


Nobody really wants their fruit machines too fancy, do they? Well, we hope not because you aren't going to be treated to anything mind-blowing in the design department. This doesn't necessarily come as a criticism as this game doesn't pretend to be anything other than a classic fruity and if this is what you're after, then you're going to be more than satisfied with the audiovisual results.

There are several ways to enjoy the simplistic design and all the action that Big X offers, and this includes mobile phones as well. You can load this title up on your smartphone whether you have an Apple or Android device.

Game Play

Sometimes it's nice to play a game that doesn't complicate things by adding too many convoluted modifiers and features to the mix. What you can look forward to is a simple base game with loads of traditional fruits doing the rounds but you have the added excitement of mystery symbols and that Big X that could land from time to time. The Big X feature does add a little variety to the setup and is, without doubt, the place to grab the biggest wins as well.

Win Potential

Nobody is going to be racing out to buy a Premier League football team with the max 500x win that this game offers. But on the plus side, you should see plenty of average-size wins hitting the reels fairly regularly thanks to the low/medium volatility. Hopefully, Big X will go easy on your bankroll while you wait for mystery symbols and the main feature to arrive.

Our Verdict

What this game perhaps lacks in sex appeal, it more than makes up for with a simple approach to slot entertainment that won't give you a migraine as you try to figure out what's going on. Hit the spin button, watch the fruits fly and just hope that those Big X symbols are waiting on the middle reel.
