Understanding the terminology used in slot games can be cumbersome - below we explain the most commonly used terms that all of the online slots have in common.
In the world of online gaming, their are various software platforms available that the online casinos use.

The reel on a slot machine is the wheel that has the various images on it. The reels are spun and then stop randomly. The position of the various images on a reel when stopped and the pay line(s) selected determine if and what the player has won.

What is a Pay Line?
Pay lines are the lines on the screen that, when the appropriate symbols line up on them, cause the lights to flash and the sounds of winning to fill your ears.
Pay lines on machine range from a single pay line slot machine to a multi pay line slots, that could have as many as 243 pay lines! Pay lines can run horizontally, vertically, diagonally or even follow no fixed pattern. So be sure to check the online slot game that you do choose as to how the pay lines are defined and how many pay lines are supported.
The number of pay lines activated is usually determined by the amount you bet on the spin of the reels. Also be sure to check when, and what pay line, the progressive jackpot pays out (if the game does have one). You don't want to hit the symbols on the correct pay line, and then find out later, to win the progressive jackpot, you had to deposit another 10c!

The slot games that have the progressive jackpot feature, usually require that the maximum bet is placed before the progressive jackpot feature is enabled.
