Online slot machine games use the same system as in traditional casinos but of course there is no mechanical system involved apart from the computer on which the slot is played. Online slot games actually resemble real slot machine entirely. They also have a random number generator like in machines that you can find in land based casinos. So the system with which they work is almost the same.

However, there is one major difference. Online slots and video slots offer mostly often higher jackpots than traditional casinos. Video slots have in general more reels and also more symbols or pictures on each of the reels than a physical slot machine. With a higher number of reels and symbols and therefore more opportunities to win, the jackpot is also higher. The mechanical slots were mostly constructed with three to five reels. Each single reel had between 10 and 20 symbols. In consequence the number of reels and symbols is less compared to the virtual games. A video slot machine can have up to 100 symbols on every single reel. In consequence, the jackpot for the mechanical slot machines needed to be limited in order to make the games profitable.

With the various opportunities that the virtual slot machines provide the odds of hitting a lucky combination change tremendously which allows online casinos to offer much larger jackpots. You will find the biggest jackpots online with the progressive slots. The symbols and pictures on the reels are in the end just images so the amount of them does not really matter in the only casino world. They do not affect in any way the payout percentages since those ones are created by the random number generator.

Reputable and trustworthy online casinos usually have an independent audit institutions checking on them regularly. Every good online gambling provider knows that it is necessary to give their customer the feeling of security and trust. Bad reputation travels fast on the internet and bad seeds in the industry will be blacklisted soon.

On the old mechanical slot machines the payout percentage was determined by the quantity of reels and symbols on the reels. For example, a mechanical slot machine had been created with a certain amount of pictures per reel. If you know the number of reels and symbols it is easy for you to calculate the probable outcome of a specific combination. You only need to multiply the number of symbols on the reels against each other. If a three-reel slot machine has 20 different pictures on each reel, you could find the amount of possible combinations in the following formula:

20x20x20=8,000

In consequence the chances of hitting a jackpot are 1:8,000. The calculation is quite easy. The players need to insert coins worth total $8,000 so that the machine hits the break even. The slot will only make profit if the payout is less than that.

online slot machines are totally different. They can be programmed accordingly not considering the number of reels and symbols on each single reel. This is mainly the reason why online slot and video slot games are able to have higher jackpots and to offer larger payouts as well.
