What is a progressive slot machine? And how does this work online?
Online slot machines are similar to their brethren in land based casinos, in that some are stand alone individual machines that build jackpots as people play that machine and that machine only.
Other slot machines are grouped into a network (the so called progressive slots). As you can imagine, on the Internet it becomes easy to network hundreds and even thousands of individual games across seperate casino brands into a huge jackpot payout. These progressive accumulating jackpots can often reach values of over a million pounds (in fact some of them start at a million).
The thing to look out for is the software that powers the casino. This will then network across different casino brands and companies to give you the big payouts. So, for example, you have the Microgaming progressive slots (powered by Microgaming casino software). An good example of this is Ladbrokes Casino Slots. Famous progressive jackpots at Ladbrokes are: Major Millions, Cash Splash, King Cashalot, Mega Moolah, LotsaLoot, Tunzamunni, Treasure Nile and WowPot
Then you have other companies such as Playtech, Cryptologic and Boss Media who are also powering these big jackpot games. Search around, and read the payout information before you play. You will probably find that you will need to play the maximum bet to be in with a chance of scopping the big one.
