Book of Blood (NetGaming) – Review & Demo Play

How to Play Book of Blood

I press the red circle with a black twisted arrow to spin the 5 reels with 3 rows each. I set the coin value before every spin, from €0.01 up to €5, which sets a total bet from €0.10 to €50. Hitting the max sign jumps me to the highest stake in one tap. I can run automated spins from 10 to 1000 using the play icon with a curved arrow. Tapping the + sign opens rules, the paytable, general settings, sound, and screen size on desktop or mobile.

I like how clear the panel is in Book of Blood. The spin control sits central, bet steps respond fast, and the info panel keeps wins and balance tidy. With 10 paylines across a standard layout, it feels familiar from the first spin. The interface handles portrait or landscape without fuss, so I can switch devices mid-session. The basics are straightforward, which lets me focus on timing, stake size, and when to let autoplay carry a run or step in.

Symbols and Payouts in Book of Blood

Prizes equal each symbol’s value multiplied by my coin value. There are nine regular symbols. Playing card values from 10 to A carry themed trims and pay 5 to 150 times the coin value. The Bat pays 15 to 200 times, and the Coffin matches that range. The Chalice filled with blood pays 25 to 500 times. The Vampire pays from two of a kind, landing 10 to 2500 times the coin value for two to five on a payline.

The Book with a cross works as both Scatter and Wild. It substitutes for missing regulars and pays anywhere in view, from 20 to 200 times the coin value. When three or more Scatters land, I get the feature, but even two can matter for line help thanks to the Wild role. Seeing these books drop in clusters sets up the bonus nicely, as they can complete awkward lines while still paying their own way across the reels.

Best Book of Blood Bonus Feature

I can catapult my way into free spins with the Buy Bonus. Paying 80 times the total bet takes me straight to 10 free spins. Landing three or more Scatters also awards 10 free spins, and doing it again during the round adds the same number. The Scatter counts wherever it lands, so triggering back-to-back rounds is on the cards. This route suits me when the base is slow, while the buy option is for when I want action now.

Before the spins start, one regular symbol is selected as a Special Expanding symbol and stays that way for the feature. After line wins pay, expansions can take over reels and pay like all regulars on all paylines, even in non-adjacent spots. This is where the game can push out big totals, as five reels of the chosen symbol ignore gaps. I've seen even low-tier picks swing sessions when the expansions line up more than once in a cycle.

Free spin mode creates an extra reel, shown as a sixth Bonus Reel. Each time at least one expanding icon is visible, that reel respins to try and add more expanding icons. The respin continues until no new icon lands, or all five main reels have one collected above them. When the respins finish, reels with a collected icon are replaced with the special expansion if there are enough to pay. It feels tense and can snowball fast.

RTP & Volatility for Book of Blood

I rate Book of Blood as a high volatility slot with a theoretical RTP of 95.58%. It runs on 5 reels and 10 paylines with stakes from €0.10 to €50, so I can scale my risk to the session length. The swing can be sharp in the base, but the bonus can hit hard thanks to the expanding mechanic and the extra reel. I use the buy option sparingly, as 80x the bet asks for a bankroll that can handle variance.
