How Do Book Slots Work?

Book-themed slots for Bitcoin are one of the classic and most widespread games at online casinos. Although the first version of Book of Ra by Novomatic was released more than 15 years ago, the world's leading providers keep releasing new remakes available for crypto players. The unique mechanics and the potential for massive winnings make this game so popular.

Even though every provider tries to introduce some distinct features in their games, Books is generally an Egyptian-themed 5-reel, 10-line slot. The book symbol plays the role of Wild and Scatter, triggering the bonus game.

3 or more Scatters award 10 free spins that constitute the game's main point of interest. A special symbol is randomly selected at the beginning of the bonus round. It expands to 3 positions on the reel and pays regardless of whether it appears on consecutive reels or not.

For instance, five top symbols on the bonus in the original Book of Ra for Bitcoin pay 5,000x of the bet. However, one should remember that high-paying symbols come with higher volatility. Therefore, many players prefer to get a medium or even a low-paying symbol with satisfactory potential, acknowledging that the maximum multiplication is unlikely.
