              <p>There are many different types of online slot machine games available to the public nowadays. Since Charles Fey invented the first slot machine in 1895 everything imaginable has been done to this popular sport to improve the excitement, especially at online casinos. Besides the simple 3 reel slots you have 20 to 50 betline slots. There are interactive slot games with bonus game features embedded within the spin modes. But there is nothing like the jackpot slots to keep a player coming back for more.<br /><br />&#13;With the popularity of online gaming growing year by year there are more people playing jackpot slot machine games online. The more people that play, the more money is available to increase the amount of the jackpot. The most popular jackpot slot games on the market are Progressive Jackpots. Progressive jackpots grow more the more players are using them. Normally a progressive jackpot is operated and promoted by the online software provider in conjunction with the software provider's partner online casinos. The software providers might have as many as 50 casinos using there online slot games. Every time any one of the players at any one of the online casinos, spins the reels 3 to 4% of the wager will be accumulated in a special account of the software provider. This is the money that will eventually be paid out to the winner. So there could be thousands of players every day adding to the winning sum of the jackpot. Sometimes you can see directly on the slot machine game board the amount of the current jackpot. The amount normally has the last two figures going higher and higher every second. You can actually see the jackpot in real time grow and grow. It is impressive really. I have seen progressive jackpots of $5,000,000 and up. These are truly "Life Changing Jackpots". I would imagine it would be quit a shock to win one.<br /><br />&#13;Not all Jackpots are progressive. Some Jackpots have a set amount and do not changing. These can be equally attractive. One of the big advantages of these set prize jackpots is that you have a better chance of wining. True the amount could be less than a million euros but it would be more realistic to think that you could walk away with the prize. Many of these type jackpots are won by matching 5 symbols up on an active beltline. Or too, they could be won inside an interactive bonus game feature. Interactive bonus game features are more and more the fashion. I see more and more interactive slots being released everyday. There was a time when they were unfamiliar to the public. But nowadays more than half of the newly released slot games are interactive.<br /><br />&#13;The last type of jackpot you will find online is a type where you do not leave the bonus game mode until you claim it. These of coarse are of a smaller scale. You can see these jackpots ranging from a few hundred dollars to one or two thousand. Lucky frog by NetEnt is an example. When you hit three frogs on an active betline you enter the bonus round. In the bonus game round you spin the jackpot wheel. The wheel must land on one of the 3 jackpot sizes. Depending on the amount of your wager you will have a better or worse chance of landing on the larger jackpot amount.<br /><br />&#13;When Fey was alive the jackpot amount had to be very small. There was only 3 reels with 10 symbols on each reel. So there was not enough combinations to grant a large jackpot. Now there are 5 reels with more than 50 symbols per reel. This alone let the jackpot amount out of the box. Now for a jackpot amount the designers could program a 15,000,000 to one chance of winning a jackpot with a five reel slot containing 50 symbols each.<br /><br />&#13;If you are serious about wining a large progressive jackpot then it would be best to focus on one that you can play away from home. Many avid jackpot chasers try their luck between lunch breaks and on vacation. So a no download slot game offered by flash casinos is what you need. These are also Mac compatible. A no download casino can be played on a computer that is not yours. It would not be recommendable to download a program into a computer you do not own. The information privy to you and the casino could be compromised once you leave the play. So take this under consideration while choosing a progressive jackpot to play on.</p>
