There are a number of different slot machines that are available for people to play in today; so many that the category of slot machine is not enough to adequately categorize them all. They are now divided into sub-categories of slot machine and these different sub-categories go a long way towards classifying the different types of machines and making everyone aware of exactly what kinds of machines they really are.
One of these machine sub-groups is the sub-group of progressive slot machines. Progressive machines have a number of interesting things going for them and indeed right after video slot machines they are considered the second most popular group of slot machines from the customer point of view. However, when one takes into account the fact that many video slot machines are also progressive slot machines, you can make a very good argument that progressive slot machines are in fact the most popular form of slots around.
The main thing that people tend to find attractive about progressive slot machines is the fact that they have a progressive jackpot; a jackpot that they derive their name from. Whenever someone spends money at a progressive slot machine, part of what is spent is added to the jackpot. The jackpot then keeps on growing as people keep on playing and it replaces the top prize on the slot machine. Therefore, if 2000x was the prize for a triple seven slot machine with maximum coins being spent each turn, that prize would then be replaced by the progressive jackpot.
Therefore, the jackpot continues to grow until somebody wins it and in this way you have a slot machine that allows someone to win big money well beyond what they could expect to win from the non-progressive slot machines that share the arena along with their progressive counterparts. This jackpot and the promise of big money is what keeps people coming back to progressive slot machines and why you should consider playing them if you are already a slot machine fan.
As far as an actual strategy to employ against progressive machines is concerned, there is very little that one can do in order to engineer themselves towards winning the progressive jackpot. There are a number of suggestions out there about how to play slot machines to increase your chances of winning and the only two that really make sense are to wait until someone has played the machine for awhile and not won anything and also to try and play machines in areas that tend to not be used very much. Machines that are in front of washrooms or loud and high traffic areas are likely machines with a higher payout percentage simply because of the fact that fewer people choose to play there.
So there you have it; you are now an expert in understanding the ins and outs of progressive slot machines. What you do with this knowledge is up to you, but at the end of the day you already have a better knowledge of how progressives work and how to play them than the average person playing at a casino.
