    Best Casinos for Online Slot Machines:

    Online slots or slot machines in general are based on the traditional mechanical one armed bandits of a classic land based casino, as technology has developed it has been made possibly to create virtual video slots, fully animated, automated and completely random. With the leaps and bounds that have taken place in the technology our favourite sites run on, online casinos have been able to offer a plethora of fun, bold, innovative and captivating online slots. They simply just keep getting better, the graphics and themes can be out of this world, with gargantuan progressive jackpots, ingenious bonus games and ways of winning casino rewards, free spins, clever promotions and prizes. As the technology has advanced so has the ability to ensure a fair gaming experience, on secure and safe betting sites. The well-known games developers are all independently checked by third party bodies to ensure they are offering a truly random gaming experience, which is fair and secure for the players.

    The video slots machines that online casino use encourage the player to play multiple lines, specified by the manufacturers to give you a greater chance of winning. In a 5 reel slot game you can often have up to 20 or so lines and numerous variations in which you could win. Although by playing many lines you are spending out more money, you are encouraged to do so to open up the bonus games associated with the slot. These can often give you big pay-outs that make up for any loses, but as with any gambling situation you may not reap the rewards so never spend more than you can afford to lose. Chasing that elusive jackpot or exclusive promotion is certainly not worth financial worries and hardship, there certainly and seriously is no fun in that!

    Every slot game is designed around a pay-out percentage, these can vary from game to game and depending on the slot machines popularity and jackpot. The online casino you choose to play at should have clearly defined wagering and pay out information for all of its games and bonuses. We believe in transparency and clear cut casino rules, at Online Casino Monsters, if the casino online is not clear about this and they are not firth coming with information when you ask them then we would advise you to avoid dining out there!

    History of Slot Machines

    The history of the slot machine is quite interesting and colourful although it all depends on which version you choose to believe. There are two different accounts of how the very first slot machine in the world came into existence. The one story is about a man named Charles Fey who had developed a simple gambling machine which he had named the Liberty Bell machine.

    Fey introduced his machine in 1887 and the contraption featured three reels and five simple and rather iconic symbols including a spade, a diamond and a heart – all relating to three of the four playing card suites (clubs are considered unlucky). Fey also embellished this with a lucky horseshoe symbol for the superstitious as well as the iconic Liberty Bell which no doubt roused the patriotic spirit of many would be gamblers who tried their luck on Fey’s simple machine.

    The second account of how the world’s first ever slot machine came into being is equally interesting and believable. This version contains two inventors named Pitt and Sittman who introduced their gambling machine in 1891. It must also be noted that some historians believe that Fey only introduced his Liberty Bell gambling machine in 1895 which would put it well past the introduction of the Pitt/Sittman machine.

    The interesting thing about this version is that it sounds quite a lot more like the forerunner to today’s online video poker machines and not all that much like slot machines as we know them. The machine was based more or less on poker and used fifty poker cards on five reels. This meant that there were ten poker playing cards on each reel. The five reels spun independently of each other and, when brought to a halt, would display a possible five card poker hand. The better the hand, the more the gambler was likely to be paid out, sound familiar?

    There were of course certain similarities between the two machines, particularly regarding the actual mechanics of the games. Both the Fey and the Pitt/Sittman versions required the gambler or player to pull a lever located on the side of the machine to engage the reels and both required a coin to be deposited in a slot before the lever could be pulled. The lever was a mainstay and all subsequent slot machines featured it, leading to the popular term ‘one-armed bandits’ which not-so-subtly alluded to how players were robbed by the slot machines.

    Online Slot Machine Rules

    The rules of online slot games will often differ from one machine to another and from one manufacturer to another. The basic rules in online slots however remains more or less the same. To start any online slot game a bet has to be made and, in online slots and most modern brick and mortar casino slots, this is achieved through selecting different buttons on the machine face. Most online slots will offer several options including being able to select the coin size as well as the amount of coins per spin or per pay line. You can also simply select the “Max Bet” button which will automatically place a maximum coin/maximum payline bet on every spin. You will also need to ensure that you have sufficient credits to play the slot machine as the online versions of most slot machines will automatically deduct funds from your online casino player account.

    Tips For Playing Online Slots

    As most experienced online and brick and mortar casino gamblers already know, playing online slots is mostly about luck and timing. This is not to say that every slots player, particularly online slots players, can’t benefit from a few useful tips on how to get the most out if their time playing online slots.

    • Pick your online slot machine carefully: Most online slots players agree that picking the right online slot machine at the right time can have a significant influence on the outcome of a slots playing session. Some online slots machines offer added game features which make winning easier while other also offer free spins which can add quite a lot to your bottom line score.
    • Read the online slot machine t’s & c’s: It is important to always read the terms and conditions on each and every online slot machine before you start playing. This will ensure that you know how many coins wins the jackpot, what the maximum payout is, what the minimum coin size allowed is and so on.
    • Watch your online casino bankroll: This is especially true of online slots as the funds per spin or per round are automatically deducted and, if you are chasing a big jackpot win, it is very easy to forget how much you are spending (or losing) per online slots session.

    Popular Online Slot Games

    There are hundreds and hundreds of different online slot machines to choose from, especially at online casinos where every online slot is ‘virtual’ and the amount of slot machines available is much larger than land-based casinos. Some of the most popular online slot games includes themed video online slots like the Marvel Comics series including Iron Man, The Incredible Hulk and Fantastic Four. Other top online slots include NetEnt’s amazing five reels slots such as Starburst, Gonzo’s Quest, Guns N’ Roses and many others.

    Popular Software Providers For Online Slots

    If you are looking to get into online slots and need to know which branded online slot games are the best to start with then a good place to start is with the classics. Microgaming and Playtech are two of the oldest software providers in the world and between them have defined the online slots industry. Other top providers includes NetEnt (Net Entertainment), IGT, Cryptologic and NextGen Gaming.
