When a casino celebrates the payback percentages of its slot machines, it's most likely that they are speaking only of a select few of their machines that are actually paying the advertised high percentage back
Slot machines in casinos across the USA typical payback between 80% and 98% of the money put into them
In Vegas itself though, there is much more competition for slot machine players so the payback percentage is usually in the region of 94-98%
Play at slot machines in airports, local restaurants and bars and you're simply giving away your money. Some say the payout percentages on these machines can be as low as 40% (i.e. 40 cent return on every dollar bet)
It is your responsibility, if destiny favors you, that you receive full payment when hitting a jackpot. Even with some relatively small jackpots, if the slot is short coins in the hopper, you'll receive only a partial cash payment in the tray, with the balance to be paid by a slot attendant. If you were to insert more coins and pull the handle, say bye-bye to the remainder of your jackpot.
If you can't afford to play the maximum amount of coins, you shouldn't be playing that denomination of machine. If dollar slots are too rich for your blood, drop down to a quarter machine. It's always better value to play five quarters against one dollar or five nickels instead of one quarter.
The slot machines by the door wont necessarily payout as much as you've heard that they will
Read all the posted material on a slot machine. It is your responsibility to fully understand all printed information concerning the number of coins to insert, lines needed to be lit, prizes or awards. In most cases, when someone calls a slot attendant over and complains the machine "just ripped me off," that individual generally didn't read the pay schedule correctly.
When you insert coins, don't assume all the tokens register before you pull the handle. Played five but only four recorded? Sorry. You'll get a sympathetic pat on the back from the casino, but no money.
Before you walk away from a machine, don't forget to press the cash-out button. Millions are lost each year by gamblers forgetting their winnings (stored credits).
Track your losses and stick within your budget
It is recommended not to play back the credits you've accumulated. Cash out and take stock. The problem with playing back credits is that the longer you stay, the machines built-in advantage eats away at them. It doesn't take long to zero out.
Avoid machines that use video representations of symbols. With these slots, there is absolutely no way to figure out what the payoff percentage of that machine is.
The best of my slot machine tips is that you should stay away from any slot promotion that sounds too good to be true. Chances are, it is!
Try not to play 2 or 3 machines at the same time. You might turn around and find your purse or some other personal item missing
Most casinos will hold a slot for you while you go to the restroom, take a short break or even go on a buffet run. Just ask a slot supervisor to reserve your machine and give a specific time when you'll return
