Progressive slot games work just like any other standard video slot game except that a tiny fraction of the money paid into the game goes into a separate pot which is unlocked only when a particularly rare combinations of symbols comes up. Slot games are programmed to pay out a particular percentage of all of their takings with a minimum set by law in the particular jurisdiction. Usually this is somewhere between 75% and 98%, with most online slot games coming in more towards the top of this scale. This is achieved by choosing winning combinations of symbols using mathematical models that ensure that over enough spins, to balance out the randomness that any individual spin of the reels is subject to, the set percentage of takings will be paid out in winnings.
In progressive slots the percentage paid out in normal play will be slightly less, usually a fraction of a percent. The difference goes into the progressive jackpot fund with is connected to a single or small number of the rarest potential combination of symbols. The mathematical likelihood of that combination coming up on any single spin will be tiny. The jackpot’s balance builds until someone wins it, meaning that the figures are often mind-boggling. It is the chance of huge wins that keeps players entertained and happy to have their chances of winning in normal play reduced ever so slightly.
