Bolt X UP, Alchemy Gaming's latest instalment of the series, is an electrifying title that pushes their X UP mechanics to their limits. A lot of slot machines have been released over the years, but nothing as popular as Africa X UP, which made a huge impact on the industry instantly. They have since been followed by Chronicles of Olympus X UP and Bolt X UP, but is Bolt X UP a worthy addition to the X UP series?
The Bolt X UP slot has many of the features we are so familiar with, including the Upsizer, and X UP features that we love so much. However, the statistics of the slot are significantly lower than that of its sibling, Chronicles of Olympus. The Chronicles of Olympus is the 2nd instalment in the X UP series. And as a result, it was expected to be a bigger and better game than the first one, and that's what it was, with a massive win capacity of 50,000x. This time around, Alchemy Gaming seems to have taken a step back and toned it down a bit with a winning capacity of 10,935x and volatility of Medium.

Bolt X UP: Theme & Graphics

It is true that the graphics of the game do not seem the best, but they are clean and crisp, which makes the experience of watching them pleasant. As the scene opens, we see a nuclear power plant with sparks in the background and a large grid in the middle with sparks flying throughout it. When you are inside a power plant, you are already familiar with the sounds that will be heard because they are in tune with the place. There is no doubt that Alchemy Gaming provides users with a memorable gaming experience; however, this won't be a classic that will last a lifetime. Although this slot can't be said to be a replica of some other slot, we can't say that it is a stupendously original game either. It still needed a few tweaks here and there to cement its status as a classic, but it never managed to do so. There is a lot to look forward to in the future when it comes to franchises. With 243 ways to win and a standard 5x3 grid, the action takes place on a solid game board. You will receive a payout when three or more matching symbols appear on adjacent reels. There are also low-paying symbols, such as royals (10-A), which reward one or two times the bet for five of a kind. Premium icons include Bells, Bars, Sevens, and Diamonds, giving 2.5x to 4x the stake for a combination of five. Scatter symbols trigger the Free Spins round and pay 4.5x the bet for landing five on the grid. Wild symbols can replace regular symbols in winning combinations.

Bolt X UP: How to Play?

Playing this online slot is not as complicated as it sounds, but you might want to take some time to understand the controls before you start playing. In order to understand, here is what you need to know:
  1. When the three-dot icon is clicked, it will open the settings menu and the paytable.

Bolt X UP: Features

As a part of the game there are five features: a Wild Symbol, a Scatter Symbol, Upsizer Feature, Free Spins Multiplier, Free Spins, and Bonus Buy.
  • Wild Symbol
In the game, there is a Wild Symbol that appears as a W with white electric sparks above and below it. This particular symbol will expand to cover all three positions on its reels whenever it lands. In this game, only the Scatter Symbol substitutes for all regular symbols, except for the Scatter Symbol.
  • Scatter Symbol
The Scatter Symbol of the game is depicted by the logo of the game with a burning X in the middle, and is able to appear anywhere on reels 2, 3, and 4. As soon as three scatter symbols appear anywhere on the reels, the free spins feature is activated with eight free spins. The Free Spins Multiplier will increase by an X UP token when 2 scatter symbols land in the base game. Players can earn two extra spins by landing two scatter symbols during the free spins feature, which occurs on reels 2 and 4.
  • Free Spins Multiplier
There is a Free Spins Multiplier located to the left of the reels. As of now, the multiplier is 2X, 3X, 4X, 5X, 6X, 7X, 8X, and 10X. Cross marks are also included to the left of the numbers, starting with one Crossmark on 2X and increasing up to four on 10X. The free spins meter is increased by one each time two scatter symbols appear in the base game. Once you collect the first X UP token, the multiplier will increase to 2X. If you collect two more tokens, the multiplier will increase to 3X. Remember that all wins that occur during a free spins session will be multiplied by the free spins multiplier that is currently displayed on the reels when the spins are activated. As soon as the free spin multiplier reaches 10X, the free spins are activated automatically. Whenever you change your bet or participate in a free spins feature, the meter is reset.
  • Upsizer
As you will not have had the time to charge up the multiplier before activating the free spins, you could always choose to buy a higher multiplier for a calculated price, if you have not had the time to do so. Depending on your stage, you will have to pay different prices for upsizing the multiplier.
  • Free Spins
You will receive three free spins once you land three scatter symbols during the base game. When you reach a certain multiplier level, all wins during the spin will be multiplied by that level. Your winnings will not be multiplied by anything if you haven't collected any X UP tokens unless you decide to pay for it in the upsizer feature if you have now collected any. The feature starts with 8 spins, and when you land 2 scatter symbols, you receive 2 extra spins.
Bonus Buy
Bonus Buy has a higher gambling component than the usual bonus buy, and as a result, it has a bigger gambling aspect. There is a 60X wager requirement to purchase the free spins feature. After making the purchase, a multiplier between 2X and 10X will be selected at random.

Bolt X UP: RTP & Volatility

This game has an RTP of 96.22%, which is higher than the industry standard. We do not have access to the hit frequency, however, it should be reasonable in light of the other parameters. The scope of the betting options is narrow, but there are numerous betting options available. There are two levels of betting, with the lowest being $0.10 and the highest being $20. Because the game is tailored to less experienced punters, high rollers may not be interested. It is possible, however, for some of them to return to the game because of the decent maximum win of nearly 11,000 times their stake.
It has a medium level of volatility, with an even distribution of wins and their potential profitability. Wins are a good indicator of how well a player is doing, so it is important to record them at regular intervals. Even though the game isn't continuously thrilling, there are some exciting moments.
