Slot machines are a mainstay of great online casino slot gambling. They seem to have been around for as long as the technology that has existed to make them and that technology has been improving all the time. The original slot machines consisted of a box containing three reels which were set into motion by pulling a handle once money has been deposited. If the reels landed on three matching symbols, you won. Simple as that.

Current slot machines are entirely computerized. The symbols come up on a video screen as well as the "reels" are set in motion by pushing a button, although some still have a handle you can pull for that old time slot machine effect. Of course, on the web, all you have to do is point and click your mouse to set the reels in motion.

The fundamentals of a slot machine are simple. You put one or even more coins in the slot, push the button and hope three matching symbols come up.
