About 70 percent of a casino's income comes from slot machines.

Casino Slot Machine

Three 7s - A Winner
Slot machines are coin-operated machines that have three or more reels, which spin when an operator pulls a lever on the side of the machine.
The reels have brightly-colored symbols on them such as fruit, bells, numbers or diamonds. When the spinning reels come to a stop, payouts can occur for certain arrangements of the symbols displayed; for example if three 7s line up next to each other. The payout usually takes the form of coins tumbling out.
The hope of the player is that the machine will pay out more coins than are put in. Although this can happen over certain short intervals, over the long term the machines always pay out less than was inserted.
Slot machines are typically programed to pay out as winnings between 82 and 98 percent of the money played. Atlantic City machines, by law, must pay out a minimum of 78 percent of the money wagered. According to an analysis by Spectrum Gaming Group, quoted on "The Morning Call" in January 2008, the average payout rate for NJ slot machines is 91.53 percent.
There are both Straight and Progressive slot machines. The straight slot machine has a set payout schedule that never changes. On a Progressive slot machine, the payout steadily increases the longer it is played until someone wins it all. It then is reset to its starting value.
Slot machines are sometimes called one-arm bandits, because of their ability
to
leave the player penniless. The machines were originally all mechanical, but most have been replaced by
computer-controlled machines. But the basic play has remained the same.
Slot machines have much appeal because they can be played at the pace of the player, and they don't require skill. Playing slot machines should be considered entertainment. If you think of them this way, you will not be disappointed if you don't always win.
Casinos originally introduced slot machines as a way to keep wives and girl friends occupied while the men folk gambled at the gaming tables. Today, slot machines are the most popular gambling method, and are responsible for about 70 percent of the casino's income.

Monopoly Slot Machines use graphics and symbols from the popular Monopoly board game. However like all other slot machine games, the Monopoly slot machine games run on a random number generator just like every other slots game, so no amount of strategizing, wagering fluctuations, or bankroll management is ever going to alter the house edge in your favor.
The only strategy that works for Monopoly slots, or any other slots is: Don't play with money you can't afford to lose.
