Stand Alone
Loacal Area
& Wide Area Progressives.
Stand Alone Progressives: are not linked to any other slot. The machine takes a small percentage of every coin played and adds that to the winning jackpot. The payback percentage is generally small, so you should find a machine with a high jackpot, in case you hit it.
Local Area Progressives: are a group of machines that are linked together and are owned and operated by the casino. They can be found in a connected slot bank, or linked over a group of casinos (if they are owned by the same company)
Because they have a smaller jackpot pool than the wide area machines, they generally will hit more often
Wide Area Progressives: are the machines with the life changing jackpots.These are owned by an independant operator and the casino shares in the machines takings. Wide areas are linked over several different properties and because of this, the administration costs are high.
