If you walk into just about any casino
the game that dominates most of the floor space is Slots. There is a good
reason for this: Slots make up about 60–65% of a casino’s total
revenue. Billions of dollars flow through these machines each year.
Because of their popularity, slot machines come in a wide variety of
denominations and a wide variety of styles.
The original Slot Machine, the “Liberty Bell”, was built by Charles
Fey in San Francisco at the end of the 19th century. It’s been a little
more than 100 years and now Slots come in hundreds of variations and many
are run by a computer board with the output displayed on a video screen.
All Slot machines are not created equally. Lower denomination machines
usually have a lower payout percentage. It costs just as much to buy and
maintain a $.05 Slot Machine as it does to buy and maintain a $0.25 Slot
Machine. Casinos usually adjust for this by having a lower percentage
payout for the $.05 Slot Machine. Regulatory bodies set the minimum
percentage payback for Slot Machines. The current minimum in Nevada is 75%
and the current minimum in Atlantic City is 83%. Because of competition,
most slots have a much higher payback.
