Bellagio Slot Machine Payouts
So who pays for those Volcanic eruptions? Pirate Battles? Carnival Parades? and Glittering Showrooms? Slot Machines. 60-65% of casino revenue is generated by those bell-ringing one armed bandits that seem to multiply on casino floors like rabbits. So how does the average player gain an advantage and possibly win? Well... aside from cheating (which we really don't suggest you get involved in) the only way to gain some sort of advantage is to choose your slots with utmost care and discrimination.
Slot machines in Las Vegas are required by law to payout 75% of the money that goes into them, actual payout in Las Vegas is approximately 95%. Will you be the one that takes the money instead of gives it? That is up to luck, but with a little investigation one can easily learn to identify which machines are more favorable to the player than others. Slot machines are all about the payout... Red White and Blue, Double Diamond, Dick Fucking Clark, Cherry whatever. At the end of the day what every slot player needs to do is look at the pay schedule on the machine they want to play. Very often the same machine one row over will pay 5,000 credits on 3rd credit jackpot while you're playing on a 2,000 3rd credit machine. Plain and simple you're cheating yourself.
- Additionally, the only kind of slot machines allowed are electronic video slot machines. Therefore, you will not find any mechanical slots that have traditional reels - only video screens According to the terms of the compact between the state and the tribes, however, the minimum and maximum payouts are regulated as follows: video poker.
- 'Slot machines are usually adjusted to pay out as winnings 75 to 98 per cent of the money that is wagered by players. It is known as theoretical payout percentage or RTP (return to player).' Since there are no games with an RTP of 100, you'll have to settle for something lower than that.
- With over 1,200 slot and video poker machines to choose from, you'll find a full selection of your favorite games. Mandalay Bay offers a variety of games, ranging from $0.01 to $100.00.
Amaya slots are by far and away the worst slot machines for payouts with a 92% RTP average (more on that later). NetEnt make the most player friendly slot games averaging a 96.51% payout percentage. The majority of companies are within 1% of each other setting an online industry standard of about 95% for slot payouts. If you want a variety of machines but still want to maximize high slot payout percentages, check out the Bellagio Hotel & Casino, where there are thousands of ways to play including a number of high-paying slot tournaments. The Bellagio features over 2,300 reel, video reel and video poker games.
Slot Spotlights
A few notable slot machines we here at VT have found more playable, or more interesting, than the other nonsense out there like Leprachaun's Gold or Tabasco Slots or whatever.
We like machines that have the best payouts on the lowest winning spins. These will keep you going longer between larger wins and not enact the ATM-In-Reverse principle seen at many of the larger joints (Venetian being the worst we've experienced).

The Math of Casino Slot Machines
For every dollar you wager in a slot machine, you will lose 100% - Payback% of that dollar. For example, you're at Bellagio playing the $1 Double Diamond slot, wagering Two Credits ($2) per spin. According to the table, for every $2 spin you will lose 5.33% of that bet... just shy of 11¢. Granted these 11 cents don't get extracted instantly... this is computed over time. So if your bank roll limit is $10 it will take you, on average 52 spins before your bankroll is toast (under $1) and you are out of credits.
How was this number derived:
STAKE x (Payback Percentages) = STAKE x (Payback Percentages) = STAKE x (Payback Percentages) = ...
Repeat calculation until the number gets below the minimum bet - if you play long enough, you're gonna go broke. THAT is a FACT. Slot machines are entertaining, relaxing, require little thought beyond pressing a button. IF you want to truly GAMBLE, you might want to look into Video Poker, and eventually Blackjack as other options.
Granted, sometime in there you just might hit that $500 win on the Wheel of Fortune, or The Elvis progressive might shake rattle and roll $1000 your way... but the math inside the machine determines that you will in fact lose a certain percentage of your wager on each spin, and the more you spin... the more you will lose despite short runs of successful jackpots. If you find you are UP... leave. Every spin of a slot machine generates a random number that has NOTHING to do with previous numbers. SLOT MACHINES do NOT run in streaks (even if you might wish to think they do). Don't expect to get any of the money you put into a machine out of it unless you learn to press the CASH OUT button.

The above sign can be found across the street from the Palms. Although I did the study Anthony Curtis published it in the LasVegas Advisor, which is how it become well known. The'...' in the sign encompases quite a bit of information,which was conveniently left off the sign. Actually the study only says that the Palms had the lowest nickel video slotsof the casinos surveyed in Las Vegas. The small print at thebottom says, 'Independent study conducted between November2001-February 2002 on Austin Powers, Fortune Cookie, Reel'em In, and Wheel of Fortune games. They left off LeopardSpots, and the study began in October.
Observations
There seemed to be no truth behind slot placement myths. Machines on the end of a bank did no better on average than those in the middle. There was also no correlation between return and proximity to such things as the main door, table game pit, high traffic areas, and low traffic areas.
Most casinos were very consistent in their slot returns.If one nickel machine had a return of x% then all others like it also returned x%. However some casinos did mix up loose and tight machines, most notably Treasure Island and the California casinos.
Methodology
A kind and anonymous source provided me with par sheets for the games in question. The EPROM (Erasable Programmable Read Only Memory) chip is what tells the machine the order of the symbols on the reel, in some cases how the stops are weighted, how much each winning combination pays, and any other pertinent information about how much the machine pays.It is up to the slot manager to select which EPROM chip to order according to the return percentage desired. On atypical game there might be about 8 different possible return percentages, ranging from about 85% to 98%.
Each of the different par sheets has five sets of distinct reels. On video display slots the stops are not weighted; in other words all stops are equally likely. The distribution of each symbol on each reel is what determines the theoretical return of the machine. For example a higher paying machine may have more of the higher paying symbols.
On the machine itself three consecutive symbols arevisible on five different reels. By comparing actualobservations of results to the par sheets it is possible todetermine which reels the machine uses, and thus which par sheet and which return. There are various three-symbol combinations that appear in at least one but not all par sheets. So if one of these combinations occurs on an actualmachine it narrows down the possible par sheets. By playingenough the player can narrow down the possible par sheets tojust one.
To help identify the unique combinations I wrote a computer program for each game, which had the exact reel order of all 5 reels of all the par sheets. The program then counted the number of par sheets with each possible three-symbol combination. If the number was greater than 0 and less than the maximum then that combination was identified along with the associated par sheets it belonged to.
It is then a matter of simply playing the game and comparing the outcomes to the list of partially unique combinations. It only takes about 5-10 plays per machine to narrow down the possibilities to just one par sheet.
The averages in the table are actually an average of averages. For each kind of machine at each casino I took an average return. Then I took the average of these averages over the five kinds of machines I tested for.
Slot Machine Definition
There is some confusion about what constitutes a 'slot machine' or 'slot.' My definition, and that of most gamblers, is a gambling machine with either actual spinning reels or video representations of the them.
People in the gaming business and regulators generally refer to a slot machine as any gambling machine, including reeled slots, video poker, video keno, video blackjack,etc.. For purposes of statistics both casino managers and regulators combine all the electronic gambling machines together. For example, the Slot Chart in Casino Player magazine and reports by the Nevada Gaming Control Board do not isolate just reeled slots but consider all electronic games a 'slot.' Therefore my return percentages should not be expected to agree with those reported by the casinos or regulators. As far as I know mine is the only source to isolate just the return of reeled slots.

I would like to thank Rob Feldheim for helping with the slot play and record keeping. Rob helped me with most of the casinos on the east side of town and part of downtown. I would also like to thank par Sheet Pete (not his real name)for providing the par sheets, without which this project would not have been possible.
