Gameplay characteristics and rules 

To operate the course of this game properly a player should use the set of buttons by means of which the control over the main functions of Crystal Ball is performed. In casino slot machines for free their amount is not very wide so that to get right into the nuts and bolts of all the functions will not be the hardest task in the world. Below we describe the objectives of each button included to the gameplay. 

  • Depending on your preferences you can start playing this game by two different ways. The first one is launched by means of Spin knob. The reels are rotated throughout a single gambling round. When they are spinning, starting knob turns into Stop key, and a click on it can stop the drums before the round is finished. Another opportunity to begin the round is Autostart. This button resides in the lower left of the screen and has ‘+’ and ‘-’ keys on both sides of it. Using levers with these signs allows to adjust the quantity of automatic uninterrupted rolls of the reels. The amount of rotations in casino slot machines for fun can be selected in a wide range from 5 to 100.
  • To review a precise cash quantity which is on your balance at the moment, the size of stake and last win amount, consult the panel under the Spin key – it contains precise information concerning the state of your finances.
  • Near this panel you will find the knob which controls coins which are placed on stake. Using ‘+’ and ‘-’ you can make this number higher or lower, regulating this number from only 5 and increasing it up to 100 rotations.
  • In Paytable you can review the images represented in this game and how much each one of them is worth. Bonus rounds are also described in this division.
  • The black board in the right corner contains other functional buttons. These are the the buttons used to adjust such user settings of popular casino slot machines as size of your screen, soundings and other parameters. 

If you don't know how to play, read the main game rules in the corresponding section.
