Instead of having a fixed top jackpot it takes a percentage of the coins played and adds that to the award for thehighest winning combination .It has a meter on the front and shows you the jackpot. In most cases the payback is equal to the other machines of that denomination but it just distributeddifferently to give you a varying amount for the top prize. The progressive jackpots for the stand alone machines is much lower that the ones from machines that are linked together.
In-House or Local Area Progressives
