The Popularity of Online Slot Machines

Slots are by far the most popular of all casino games, which is why if you've ever visited a land or online casino, you'll have noticed that slot games vastly outnumber video poker games as well as card and table games. There are many reasons for this. One, slots are quick and easy to play, two they boast instant payouts that can range from a few dollars to tens of millions, and three, there are so many different types of slot games available, that slots fans risk never being bored.

Although the world's first slot machine was invented in 1887 by Charles Fey of San Francisco, in the USA, it was largely based on a 'poker machine' invented a few years before by a pair of entrepreneurs in New York City. Their machine contained five drums, each adorned with 10 card values (to increase the house odds, they left two cards out). Costing a nickel (10 U.S. cents) for each spin, players could win themselves free drinks and cigars, depending on whether the drums yielded a winning poker hand. The better the hand, the better the prizes.

Charles Fey's slot machine, although simpler than the poker machine, resembled more of what we today consider a slot machine to be. Famously called the Liberty Bell, Fey's machine boasted three spinning reels, each adorned with 5 symbols - Hearts, Liberty Bells, Diamonds, Horseshoes and Spades. Players won the largest amount (10 nickels) when they got three Liberty Bells across the three drums. This single game gave root to the multi-billion dollar a year slots industry of today.

Slot machines are also known as 'one-armed bandits', after their handles or levers that players were required to pull in order to spin the reels, and 'fruit machines' after the fruit symbols adorning the reels of many games. Today, players can enjoy playing slots at land casino as well as online casinos. Surprisingly, perhaps, the computer software that runs land casino slots is pretty much identical to the software that runs online slots. Called Random Number Generator (RNG) software, this ensures that each and every spin of a slot game is completely random, and thus 100 percent fair.

The Payout Percentage or RTP (Return To Player) of Slot Machines

Of course all modern slot machines - both in land and online casinos - boast what is called a payout percentage. The payout percentage indicates to players how much money played on the game is ultimately paid back out as winnings. Payout percentages usually range from between 95 and 98 percent. This means that on a game with a payout percentage of 97, of every dollar played an average of 97c is paid back out in winnings. But be aware that this does not mean you'll necessarily get back 97c of every dollar you play on that slot. It is only an average. And to ensure that these payout percentages are what the casinos say they are, they are routinely audited by independent and reputable auditing firms such as Pricewaterhouse Coopers.

Not too long ago, before the advent of the Internet and thus online casinos, slot machines in casinos were completely mechanical, much like Fey's Liberty Bell. However, modern technology has made slots more high-tech and reliable than ever before. In fact, very few land casino still have slot machines that accept coins or tokens. These days players insert plastic cards carrying pre-programmed credits or else feed paper money into the games, the value of which is transferred onto the cards. All winnings are paid directly onto these cards, which players can cash out at specific casino cash machines or directly from cashiers. In online casinos, all slot game credits are automatically transferred to and from a players account as they play.

The Diversity and Excitement of Modern Video Slots

But the thing that fans seems to love the most about slots is their diversity, both in style and theme. For instance, you get classic or 3-reel slots, 5-reel slots, single line slots, multi-line slots, bonus slots, multiplier slots and of course potentially the most lucrative slots of all, progressive jackpot slots, where the jackpots can reach into the tens of millions. In terms of playing online slots, or slots rules, nothing could be easier. You simply choose the kind of online slots you want to play from the online casino menu and click to download it.

Once it has downloaded, simply select your bet size, which can range from a few cents per line up to hundreds of dollars per line. Next, select how many lines you want to play. (In a classic slot game, there is only one pay line, but in multi-line slots, there can be in excess of 50 lines). Next check to see how much your total bet size is for that round. If you're happy with it, go ahead and spin the reels. If you have made any winning combinations - as per the game's particular Pay table - you'll be paid out accordingly. If not, then the process starts from the beginning.

Second Round Bonus Features and Free Spins

To make slot games even more exciting, designers often include a wide range of features that are designed to make the games not only more exciting, but more lucrative for you, the player. For instance, most slots boast Scatter symbols, which are symbols that can be randomly scattered on your reels to pay out. However, usually you need a minimum of three Scatters to win anything. A certain number of Scatters can also activate special Bonus rounds as well as Free Spins and even Multipliers.

A Wild symbol is very much like a Joker in a deck of cards in that it substitutes for any other symbol (except for a Scatter) to help make a winning combination. As its name suggests, Free Spins is where you can enjoy a specified number of spins for free and you get to keep all the winnings generated from these spins. A Multiplier is where your bonuses or Free Spins winnings are multiplied a specified number of times, like 2x or 3x or 4x etc. A Bonus round is where you leave the standard slot game format and are taken to a new screen where you usually have to make a choice of some type to reveal your hidden bonus or bonuses.

In terms of slot strategy, the biggest thing to remember is to always play the slots game and bet size that best represents the size of your playing funds. Also, if you are looking for the biggest payouts, your best bet is to concentrate on progressive jackpot slots games where you can win millions. But remember, there is little point in playing for the big payouts and jackpots if you don't always play the maximum bet.
