Slot machines work in the online casino basically as well as slot machines in a game room. Instead of throwing physical money, inserts will be deducted from the account. The inserts do not take a physical pressure on a knob, but by pressing a virtual button on the screen. There is a wide range of slot machines. Many slot machines common are certain features. For example, there are profits when a certain number of identical symbols lands on a gainline. How many paylines there are, is different depending on the machine. There are symbols with different value. The particularly high-quality symbols are naturally rarer. A very important gameplay affects wild icons. These are symbols that replace all other symbols (optionally except for the scatter symbol). Scatter symbols again solve free spins. Sometimes there are multipliers that increase the profit according to certain rules.
