Online Slots are by far the most popular casino game in the online gaming industry. As such, they are also the most abundantly found, and it certainly doesn't hurt that they are furnished in just about every fantastical theme the human mind can produce.
Interestingly enough, there is very little difference between online slots and those found in a brick and mortar casino. The fact is, both are based on a computer software program, running a Random Number Generator (RNG) to produce unsystematic and unpredictable outcomes with every spin of the reels. Aside from classic reel slots, with the traditional pull-lever - which are becoming increasingly rare in today's technological world - the only difference between online slots and live casino slots is the fact that you must travel to the casino to play.
Online slots give casino fans the chance to log into a secure web site, from the comfort of their own home, and play the exact same machines for real money. In the same token, one feature you certainly won't find in a brick and mortar casino is the ability to play these exciting games for free. Most online casinos offer all of their games, including online slots, just for the fun of playing them - no risk, no loss, no bouncing the mortgage check and filing for divorce when your spouse finds out!
This brings up a good point I'd like to make real fast - when playing online slots for real money, never deposit more than you can afford to lose. If you win, woo-hoo, grab the family and go on vacation! If you lose, it's not as cheery, but no big deal. You are essentially paying to have a good time - just like going out to the movies or a club - except there's a chance of winning some money in the process.
Another key point that a lot of people may not realize is that online slots actually pay out way better than live casino slots. The average live casino pay out percentage is in the low to mid 80's. An online casino, however, averages pay out percentages of 95% and up. I've even witnessed pay out percentages over 100%! The online casino chooses the RNG pay out percentage, which is set to pay out that percent over time, and as often as not, that payout is going to be higher rather than lower.
When choosing where to play online slots, the decision is often based on the software platform that powers the online casino. Today's most popular software brands include Microgaming Casinos, PlayTech Casinos and Cryptologic Casinos. These developers create unique, thrilling online slots for the casinos that license their software, so the gaming selection will be mostly the same at Microgaming Casinos, but different from PlayTech Casinos or Cryptologic Casinos, and vice-versa.
If you're new to the online slots scene, I would first suggest a trial run at one of the many Microgaming Casinos. Microgaming is the leading online casino software developer with more than 200 versatile selections of online slots alone.
