Like any land based casino, casinos online have a multitude of slot machines. In fact, playing slots are the most popular games in just about any casino.

Playing slots online is almost the same as playing them in a land based property like going to Las Vegas or Reno. The only thing that may be different is that often the slots odds in an Internet casino are sometimes higher than what you see in Vegas.

3 Reel Slot Machine
A 3 reel slot is one of the most classic of all slot machines. Different 3 reel slots may contain one to 3 and sometimes more paylines. Any time a slot has multiple paylines, your bet placed is multiplied by the amount of lines played.

As an example, if you play 25cents on a 3 reel 3 line slot, and you play all 3 lines the bet will cost you 75cents. Although it may cost a bit more for the spin, instead of having only one way to win, you now have 3 different ways you can win on that spin, thus increasing your chance of winning on each spin you make.

If you are unsure of what the paylines actually are on a slot, just load the game that you would like to play, and look for the button on the slot for the "payline" or "paytables" as this will bring up a screen that will show you more detail about that individual slot, the paylines offered, and it will also show you the values of each icon when it comes up on a winning payline.

Video Slots
The popularity of the various video slots continues to grow at a phenominal pace. Video slots differ a bit from the traditional reel slot in that they often will have 4 or more commonly 5 reels, and they will often also have 10, 15 and even 20 paylines.

In addition to multi reels and multiline payouts, video slots will often have some added features, such as a scatter icon, multipliers, and even contain bonus rounds.

Often a scatter will increase your win quite a bit if it ends up on a winning payline. They call it a scatter becuase in many games a scatter will pay no matter where it appears as long as it's a winning payline.

A multiplier, when showing up on a winning payline can easily increase or multiply your win by 2x, 3x, 4x and sometimes even 5 times what the win would have been without the multiplier.

Now bonus rounds can really be fun. Depending on which slot game you are playing, what the bonus symbol is, or where it may need to end up on the payline. Some games will require you get 3 on a payline in order to qualify for a bonus round.

Most of the different slots have different things that take place during a bonus round. Some will give you free spins, some will have you select a symbol and pay out a random bonus. I think the many bonus rounds of various types in the different games are some of the reason why video slots have become so popular.

Time and space do not really permit a more in depth discussion of video slots here. The best way to really discover video slots is to visit one of the recommended casinos and download their software and create an account.

Often you will be able to play the games for free before you decide to make a purchase and play the slots for real money.
