One of the most common mistakes is jumping straight into a game without reading its pay table. This is a crucial document that provides information about how the game pays out symbols, including its paylines and bonus features.

The rules vary between games, but they generally include the RTP rate and other important details. It’s important to read these documents thoroughly before playing a slot machine.
