Does Book of Fusion Pay Real Money?

As sure as day becomes night, Book of Fusion pays real money, along with other online slot machines at BetMGM Casino — provided you’re physically playing from New Jersey, Pennsylvania, Michigan, or West Virginia. That’s because BetMGM Casino’s games are exclusively available in those specific states.

How To Play Book of Fusion

You don’t have to be a nuclear scientist to get started with the Book of Fusion slot. Simply head for the Slots lobby on the BetMGM Casino website and launch the game on your web browser. Once you’re in the lab, press the coin stick to adjust your bet size to anything from $0.10 to $35 per spin. 

If the Buy Pass button is available, you can hit it to go directly to the bonus round. Buying free spins gives you marginally better slot game odds than regular spins, so this can be a good move (and save time), but be sure to stay within your budget.

Book of Fusion Game Features

As is usually the case with “book” slots, the Book symbol is the most important feature of the game. That’s because it’s a dual-function symbol. First, it’s a wild symbol, substituting for pay symbols to complete line wins. Second, the Book is a scatter symbol. It’s always an electrifying moment when 3, 4, or 5 Books show up on the reels because it means you get a 2x, 20x, or 200x bet payout, as well as a bonus round of 10 free spins.

Book of Fusion Bonuses and Jackpots

Book of Fusion is a great online slot for real money players because of how the Free Spins bonus works. Once you’ve triggered the feature, the Book flips open, and two pay symbols are selected as special expanding symbols. Any time these symbols can make a win during the feature, they expand across their reels, covering every position and paying every line. Not only that, but special symbols also pay from any position — they don’t have to be adjacent or start from the leftmost reel.

Things really start cooking in the lab if three or more additional Books land during Free Spins. When this happens, you get 10 more free spins as well as two more randomly selected expanding symbols. This can repeat until all 10 symbols have been selected by the Book.

How To Win Book of Fusion

Making wins in the Book of Fusion slot is country simple — merely line up three or more like pay symbols on one of the 10 active paylines to have a win credited automatically to your casino account. Normal wins pay from left to right according to the paytable, starting from the leftmost reel, but wins involving special expanded symbols pay from any position. The scientist is the most valuable symbol at 500x for a set of five, so it’s exciting to trigger Free Spins and have the Book flip to the scientist.

Book of Fusion Graphics and Design

The Book of Fusion slot plays out on a 5×3 board set in a lab where a nuclear fusion experiment is taking place. The lab is filled with weird-looking gadgets, dials, bottles, and tubes that suggest the scientist conducting the experiment has an unorthodox approach. The reels are clear, so you can see through to the stone walls and tanks in the background. 

The symbol graphics are highly original, not to say wacky, and very detailed, which brings the theme to life. As for the Book, it has a life of its own, showcasing the various symbols to full effect every time its pages flip. Needless to say, the soundtrack is as zany as any mad scientist could wish for.

Book of Fusion Symbols

For an online slot game with a hi-tech theme, Book of Fusion has some very traditional low-value symbols in the form of playing card royals 10 to A, which pay 10x to 15x the bet if you land five of a kind on a payline. Moving up the paytable (in ascending order of value) are magnets, switches, meters, electrical conductors, and a scientist with long white hair, a white beard, bright blue eyes, and a wild, quirky grin. These symbols pay out 75x to 500x the stake for five of a kind, which represents solid win potential. With straight-up payouts like that, who needs slot multipliers?
