There are two boxes on the right side that describe the bonus. Looking closely, you find that the choices do keep the same order, so it's not random, but it definitely feels like this.
There are no pay tables, instructions or charts for paylines, but they are not needed due to the way they are laid out. It is very easy to change your betting line from 1 to 8 with a denomination of 0.01. 0.02. 0.05, 0.10. 0.25, 0.50, 0.25, 5.50, 5.0 and 10.0. If you feel lucky, you can bet Max Bet gets a bet of 80.0.
