BOOK OF STARS SLOT REVIEW

Book of Stars is an adventure-themed online slot developed by Greentube (Novomatic). This game explores the secrets of the starry sky, but not from a scientific perspective. Instead of a space exploration theme, the focus is on the ancient Greek gods and their role in lighting up the sky night and day. The Book of Stars slot has five reels, three rows, and 10 paylines. It offers bonuses like free spins, Wilds, and a unique bonus bet symbol that introduces an extra Wild symbol into the mix. Book of Stars is a medium-volatility game with an RTP of 95.80%. 

ABOUT THE BOOK OF STARS SLOT 

Long before scientists came up with practical explanations of how the universe worked, ancient Greeks had their own tales to explain the cosmos, with gods like Helios, the sun god, and Nyx the primordial goddess of the night in charge of the starry night sky. 

In the Book of Stars slot, you get to explore the age-long tales of these powerful gods by joining an adventurous researcher on her quest to discover the secrets of the galaxies. It’s a daring adventure, but one that promises bountiful wealth and rewarding possibilities as you learn about the powerful gods. 

The game is set in what looks like a giant cosmic temple featuring massive statues of the Greek gods surrounded by flashing lights and glowing clouds of gas and dust. This space-like setup creates an otherworldly atmosphere that fits the slot’s theme perfectly. Unfortunately, the background music isn’t as interesting as we would have loved it to be. In fact, there’s no soundtrack at all, just regular slot machine sounds that play each time you spin the reels. 

GAMEPLAY 

WAGER

Book of Stars has a five by three grid setup with 20 paylines. The number of paylines is variable which means you can choose the specific number of active paylines you want on each spin. A winning combination is formed when you land identical symbols on adjacent reels of an active payline. You need at least three low-paying symbols or two high-paying symbols on a payline to create a winning pattern. The minimum amount you can bet on each spin is $0.20 when all 20 paylines are activated. 

SYMBOLS

The Book of Stars slot has a total of nine standard symbols. Four of these symbols are themed icons while the other five are standard playing card symbols. The themed icons include the female adventurer as the highest-paying symbol. This icon pays a maximum of 250x for five symbols on a payline. Next is the Helios symbol which pays 100x for a five-symbol-combination. The last two themed symbols are the wise owl and the Greek goddess Nyx. Each of these symbols pays 37.5x for five symbols on a payline. 

The low paying symbols are the traditional card icons. The A and K cards pay 0.5x, 2x and 7.5x for three four or five symbols on a payline. Similarly, the Q, J and 10 cards pay 0.25x, 1.5x and 5x for the same patterns. 

The Book of Stars has two special symbols (the Book and the golden ring). The star book symbol is the most important symbol as it is both a Wild and a Scatter symbol. The golden ring is only active when the bonus bet feature is activated. This magical ring acts as a universal Wild symbol in this mode of the game. 

SPECIAL FEATURES 

Like similar slots with a "book of" mechanic, the book symbol is the main bonus symbol in the Book of Stars slot. This symbol can act as a Wild, which means it will substitute for any of the other game symbols, forming or completing winning combinations. It is a paying symbol too. You can get 200x, 20x, or 2x the bet amount for landing five, four, or three of this symbol on a payline. 

Book of Stars slot also has a unique bonus bet feature. When this symbol is activated, an extra bet amount is added to your wager. In this mode, a special golden ring symbol is randomly added to reels two and four. This symbol acts as a universal Wild because it can substitute for any of the other symbols including the book symbol to form a winning combination. 

Another special feature of this game is the gamble feature. This is activated each time you land a winning combination. With this gamble option, you are given a chance to double your payout by guessing the correct color of a face-down card. A correct guess will double your payout for that round, but you’ll forfeit the win if your guess is incorrect. 

BOOK OF STARS FREE SPINS FEATURES

The Scatter symbol in the Book of Stars slot game is the book symbol. This symbol will trigger the free spins bonus round with an expanding symbol bonus feature when three or more land on the reels. 

Before the bonus round begins, one of the regular symbols is randomly selected as the bonus symbol. If this symbol forms a winning combination, it will expand to cover the entire reel, triggering bigger payouts. 

In addition to the slot’s built-in free spins round another way to get free spins in this slot game is through casino bonuses. Real-money online casinos typically give players free spins as part of various promotions and bonus packages. 

For instance, newly registered players on a top casinos like EnergyCasino may get no-deposit free games as a welcome bonus on the casino. This bonus allows them to spin the reels on selected slot games even before they deposit them into their account. Older players can also take advantage of ongoing promotions like EnergySpins rewards, loyalty bonuses, deposit bonus offers, and tournament prizes to unlock free games. Claiming bonuses like this helps to maximize your bankroll and boosts your winning chances. 

BOOK OF STARS FREE PLAY (DEMO)

You don’t have to dive straight into playing this slot game for real money. Many online casinos give you the option of playing first in demo mode before switching to the real money version. In the Book of Stars demo you’ll get virtual funds from the casino which can be used to bet on reel spins instead of wagering with real cash. 

The virtual fund resets to a default value each time you reload the game meaning you can continue playing for fun indefinitely if you want to. The demo mode has all the standard features of the premium game. The only difference is that you cannot withdraw any winnings you get in this mode out of the casino as real cash. 

To play the demo version of this slot, you simply select the “play demo” option.  For players in certain jurisdictions, no registration is required to play demo games on real money casinos. However, the law in some locations requires all players to register and verify their accounts before they can access demo games.
