Slot machines have more settings, which may somewhat vary game to game. On the whole, it is all about the size of our bet per spin, but remember that there is of course no risk whatsoever when playing for free. The winning symbols do not have to be sorted vertically next to each other, but in any other way that is certain by the pay lines that we picked, if the rules are that the pay lines are fixed. The additional pay lines we decide the improved the chance of winning, while the bet per spin is also grow. In addition to the settings that decide the size of our bet and prize, slot machines have other skin tone, which make our fun even more intense, but which are different with every slot machine.
