How to Play

Crystal Book has intuitive functionality that is easy to understand. But still, we have prepared a short guide for you.

  1. Open the menu so there is all the necessary information, which is divided into sections.
  2. Click the "i" icon; there is a paytable and everything about slot symbols.
  3. Click on the scroll icon; in this section, you will find the game's rules.
  4. Click on the coin icon next to the reel to select your bet.
  5. Choose a starting bet from those offered.
  6. Press the spin button to start the game.

Crystal Book is a slot that has a standard reel - 5 reels, 3 rows, and 10 pay lines. The bet size available in this game ranges from €0.10 to €100.

Crystal Book RTP and Volatility

8.4 
The slot has an RTP of 96.04% and high volatility.

These two indicators are very important because they determine your theoretical winnings. Let's start with an RTP of 96.4%, which is slightly above average, which is pretty good. RTP shows how much you can get back as a percentage; for example, in this case, you can get back €96.04 out of a total bet of €100. Volatility, in turn, is a measure of the frequency and size of your winnings. High volatility is often big wins, but you must wait for them for a long time, and sometimes even longer than you expect.

Theme

7 

All actions take place in Egypt. It looks like the reel is right in the middle of an excavation or temple exploration. The reel is in the background of columns, statues, and many crystals. The design of the reel itself is very simple. During the game, there are sound and visual cues, such as a melody after a spin or a melody after a win, as well as the sparkle of the symbols.

The slot has both expensive and cheap symbols, as well as one special symbol.

The low-paying symbols are the standard 10-A card symbols. The slot's high-paying symbols are the scarab, the golden Ankh, the eye of Horus, and the most expensive explorer symbol.

The only special symbol of the slot is the same Crystal Book, which is both Wild and Scatter.
