Introduction
I think the Bellagio slots are the best paying slots of anywhere in Las Vegas!! If you play the $500 machines, the payoff is better than the penny machines. Tip the CW $50 after the first drink and I promise the service will be great.
The following table ranks the Las Vegas casinos according to the looseness of their video display reeled nickel slot machines. The returns are based on a sampling of five different types of machines. The data collected goes back as far as October 2001 so the information is a bit dated.
Las Vegas 5 Cent Slot Survey
It broke the record set in October 2004 when a Toronto tax accountant won nearly $5.8 million after spending $60 on a Megabucks progressive slot machine at Niagara's Fallsview Casino. Megabucks is a slot machine system linking 11 Ontario casinos to escalating jackpots. Casinos are not able to change slot payouts, slot machines come with an already set payout percentage, when a casino places an order for a slot it specifies the long-term payout percentage it wants. Although, depending on the jurisdiction the casino may or may not be able to change the payback percentages at a later stage. 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¢.

The Suncoast and Rampart Casino in Summerlin do not allow playing slots and taking notes at the same time. I can not include any casino that prohibits the method in which I gather data.

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.
Acknowledgements
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.

Casinos are not able to change slot payouts, slot machines come with an already set payout percentage, when a casino places an order for a slot it specifies the long-term payout percentage it wants. Although, depending on the jurisdiction the casino may or may not be able to change the payback percentages at a later stage.
For example, in Nevada, casinos are able to change the slot payout percentages by ordering a new chip from the manufacturer, the chips in the slot machines are then swapped and it is only allowed when all the appropriate paperwork is filled with the state to inform them of the change. Some of the later model slot machines support downloadable software, should a casino request a change in payout percentages the software can be sent via a central server and the slot machine can be updated without physically being opened. Yet there are strict rules in place regarding software changes and the casino is unable to make these changes on any slot while anyone is playing on it.

When it comes to slots the house edge or advantage is replaced by the payback percentage, these vary from one software supplier to the next and from one slot to the other. Some of the most popular online slots offer a payback percentage of 99%, which is much higher than that offered by land-based slot machines, which offer around 79% to 85% on average. It is most important to remember the theoretical payout percentage are calculated over an extended time-period.
