Game Review

Bolt X UP Slot

Be the hero of your own story on the reels of this exciting new online slot by Microgaming. Designed by Alchemy Gaming in conjunction with Microgaming, this slot has an electric design with fantastic gameplay.

Unleash the lightning on the reels, and you can win up to 10,000x your bet thanks to massive multipliers, free spins, and expanding Wild symbols. What more could you want?

Theme, Soundtrack and Symbols

From the moment you load this Microgaming slot, you’ll feel as if you’re either a mad scientist in a lab or the hero out to stop him. Synth music blasts while each spin of the reels is intense as the symbol crash onto the screen.

Besides the crackling lightning and brilliant music, there isn’t much indication of a theme while playing Bolt X UP. And yet, it works.

The game screen is set on a background filled with lightning, and the low-paying symbols are standard A, K, Q, J, and 10. Other symbols on the reels include a high-powered pair of cherries, lightning-filled bells, crackling BARS, an electric golden Seven, and a trio of mighty diamonds.

Special feature symbols on the reels are the X UP Scatter and the Wild, which can fill the reels whenever it lands, creating huge wins along the way.

Game Mechanics

The aim of the game is to create winning combinations from left to right across the 243 ways to win. With every spin of the reels, you stand to collect winning combos, Scatter symbols, Wilds, and more.

You can play for as little as €0.10, and the highest bet is capped at only €20. While this may not be ideal for many high rollers, the slot still has the chance to pay out over 10,000x your bet thanks to free spins multipliers that climb up to 10x.

The theoretical RTP of Bolt X UP is set at 96.22%, which is just above average for an online slot of this style and pay-out ability.

Special Features

Don’t miss your chance to unleash the power of lightning on the reels of this Microgaming slot by unlocking the bonus features.

Bonus Buy - If you’re unwilling to wait for your chance to arrive at random, you can smash the Buy Bonus button. Using the Buy Bonus feature means that you can purchase free spins. You’ll receive 8 free spins with a random multiplier that can range between 1x and 10x your bet. Take note that the Bonus Buy feature comes at a price of 60x your regular bet. If you’re betting for the full €20 per spin, buying 8 free spins will cost you €1200.

X UP feature – Land 2 Scatter X UP symbols on the reels at once, and you’ll receive an X UP token. These tokens must be collected to receive multipliers during free spins. You can see how many tokens you’ve collected on the multiplier bar to the left of the game screen. Any tokens you receive are tied to your bet amount. If you change how much you’re betting, you’ll lose all stored tokens – so choose wisely!

Free Spins – Land 3 or more Scatter X UP symbols, and you’ll be rewarded with 8 free spins. If you land 2 or more Scatter symbols during the free spins game, you’ll receive an additional 2 free spins. You can also increase your multiplier as you play through the bonus feature.

Play ‘On The Go’

All slots created by Microgaming, whether by them personally or by one of their smaller studios, such as Alchemy Gaming, can be enjoyed on the move. This is because they use the latest HTML 5 technology to craft their casino games.

Thanks to HTML 5, you can use your mobile browser to enjoy everything Bolt X UP offers. Simply visit one of the Microgaming casinos of your choice and start playing. There’s no need to download any additional software or apps.

CasinoWow Game Verdict

If high-energy slots with crackling bolts of lightning and exciting gameplay are what you’re after, don’t miss Bolt X UP. This is a fantastic slot by Microgaming and Alchemy Gaming which CasinoWow highly recommends. Experience the big winning opportunities with every expanding Wild and collect massive multipliers while you spin!
