A slot is a narrow notch or groove, such as a keyway in a piece of machinery or a slit for a coin in a vending machine. The word can also refer to a position in a group, series, sequence or other arrangement. For example, a person can book a time slot at the gym or a customer might reserve a parking space in a lot.
Slots have come a long way from the pull-to-play mechanical versions that littered casino floors decades ago. Nowadays, the floors are aglow with towering electronic contraptions that boast eye-popping graphics and sound effects. But before you head to the casino and start pulling handles, be sure to do some research on how these machines work.
Read the Pay Table
Each slot has a pay table that displays the regular symbols and their payouts. It will also highlight any special symbols and their functionality. If the slot has a bonus feature, you will find information on how to trigger this in the pay table as well.
Another thing to look for in the pay table is the variance of the slot. The higher the variance, the less likely you are to win. However, when you do, you can expect to win large amounts of money. This is why some players prefer high-variance slots over low-variance ones. The variance is calculated as the amount of money won (paid out) divided by the amount of money played (paid in) over a certain period of time.
