Alchemy Gaming and Microgaming have so far collaborated on a series of great slots, the most notable Wheel of Wishes, and the two X UP slot games, Chronicles of Olympus X UP and Africa. These slots rely on X UP Scatters that trigger special features and modifiers that create immersive gameplay action that can lead to wins worth over 10,000x the stake. The X UP series is back again in a slot called Bolt X UP.

It’s a slot with 243 ways to win and medium variance paired with an RTP of 96.22%. The slot’s maximum winning potential hits 10,000x the stake, and for that kind of money, you need the X UP Scatters. Just like its predecessors, it comes with action-packed and electrifying gameplay where multipliers promise excellent action.

The Upsizer feature is paid but steals the show in the Free Spins Round where you can pay for higher multipliers and winning potential. The Bolt X UP online slot is now available in every Microgaming casino for free and real money.

Bolt X UP is a lightning-themed sci-fi slot set in a lab of some kind. It reminds us of Tesla’s lab with all those machinery-producing bolts in the background. Layout-wise, it’s a 5x3 slot game with all kinds of symbols on the reels powered up by lightning bolts.

The paytable says that the Wild pays the most – 5.40x for five of a kind. Among the premiums, the diamonds lead the list with payouts of 4.80x for the same combination. They’re followed by seven, BAR, bells, and cherries. This is a throwback to good ol’ Vegas slots, but we love the art direction and the lightning surrounding the symbols. The symbol list is completed by low-win card royals.

Visually, the slot is as impressive as it gets. We’re a bit disappointed the lightning doesn’t go live like we hoped. The audio is spot-on too, with a range of excellent sound effects that immerse players in the atmosphere. And we love that Nintendo-like theme – it suits the slot well.

The Bolt X UP slot works great on any mobile platform thanks to the HTML5 engine it was developed on. You can give it a spin on any Android and iOS device without the need to download slot apps.

Place a wager from $0.10 to $20 per spin and start the game by hitting the Space button. As mentioned earlier, all spins begin with 243 ways to win. Expanding Wilds are active in all stages of the game and are key to big wins in the base game. Landing two Scatters on the same spin awards an X UP token that’s collected immediately in the multiplier meter to the left. This one can unleash multipliers up to x10, but only in the Free Spins Round.

Five Wilds pay 5.40x and they also expand to cover the reel. If you’re lucky enough to land a full screen of Wilds, their payouts are combined for a total of 1,093x the stake.

Triggering the Bonus Round is possible three X UP Scatters on reels 2, 3, and 4. You get 8 free spins and a global active multiplier depending on the meter filled before. A total of 23 Scatters collected in the base game upgrades it to x10, which is a nice boost that can lead you to the maximum possible win in the game.

Players also have the option to use the Upsizer feature which allows them to pay for a higher Bonus Multiplier. The number of collected Scatters can reduce the price. In some jurisdictions, players can buy the Bonus Round for 60x the stake, with a random Bonus Multiplier up to x10 attached.

The Bolt X UP slot RTP is set to 96.22%, which is excellent for medium volatile slots. With a bit of luck and a high multiplier, the maximum you can win is 10,000x the stake.

Bolt X UP is another nice entry in the X UP series by Alchemy Gaming and Microgaming. It follows the action of its predecessors while adding electrifying X UP Scatters to the mix. It’s somewhat of an homage to old-school slot games, with modern features such as collectible Scatters that upgrade the Free Spins Modifier.

The result is lightning of a slot that pays truly well, and a game no player should miss at the top-rated slot sites.
