How to guesstimate slot machine payback percentage?

Unlike video poker, there's no way to know the exact return % for a slot machine. However, sometimes we need to accumulate some points on slots for camouflage purposes.

All I know is that:
Higher denomination return more than lower denomination.
The fancier the machine, the lower the return.
Some progressive slots and accumulative slots can be beaten, but it might not worth the time to scout.

When you walk into a casino, how to estimate which slot has the highest return?
Old fashion 3 reel fruit slots vs ugly multi-line video slots, which tend to have a higher return?
$1 dollar denomination fruit slots, play 3 credit vs 1¢ multiline video slots, play 60 lines 5x bet. Both plays are $3 per bet, which tend to have a higher return?

This may be old news, but there are slots (at El Cortez) that tell you your payback based on your bet. I assume this is something new, more or less, though I don't get to the casinos as often these days.

You have a few of the keys already. I was a Slot Director for a short time. Here are many of the ways to get a lower house edge machine:

Do not play any TV, movie or celebrity themed game. They cost the casino more in revenue sharing (they also cant be purchased), so the hold is always higher.

Higher denomination games are almost always a lower house edge. If you are going to play $3 per spin, play a 3 credit dollar machine rather than 300 credit penny or multi line quarter machine.

Look for machines with no progressive. Progressive take some of your money and you have a slim to slimmer chance of winning it. Machines with 4000, 8,000 or 10,000 credit top pays well generally pay back better than larger ones and progressives.

Play machines in the middle of a bank. Many casinos use a lettering system or some other way to classify machines by their real estate value. A machines are on the ends of banks or on 2 and 4 machine islands. These give players more room, so many places increase the hold. B machines are the second machine in on both sides of a bank. C and D are middle machines of 5-8 machine banks. A lot of times you can get 1 or 2% lower hold on these machines.

Another factor in how fast your money goes, but not necessarily related to the hold is volatility. Every manufacturer now rates their machines with a volatility scale when they pitch it or install it in a casino. You don't have access to this, but there are two things you can do to help. One, search the internet for low volatility slots. There are sights that talk about them once in a while. Some people also call the "trickle" machines or "trickle back" machines as you get a lot more wins but some/many are the same as or less than your bet. Second, ask a slot department which machines are lower volatility. Most wont know. Many will look at you with a dumb look on their face. But some will know. I would tell players which ones were less volatile if they asked or if I knew a friend was going to be playing.

That's all I can think of right now. Good luck!

Well there's a couple things you can do.

1) Figure out the HE of the machine. Shouldn't have to explain this one.
2) Find out the state minimum in your state, you can always use that as a "worst case" scenario benchmark.
3) Look up the casinos pubic records to see the "average" per denomination in any casino/slot house.

When you put 2 and 3 together you can usually get a decent "guess" and play a % or 2 against you to be safer...

The Ellen game was actually really good in like its first week, giving frequent $300 wins on $1.50 and then went to crap after that. So I would say play a Celebrity themed Slot only in its first week.

I have found one exception to my "dollar slots tend to be looser than quarter slots, which in turn are looser than penny slots" rule - Megabucks. If you check the numbers for gambling earnings by the Nevada casinos, Megabucks has a much lower return to player percentage than other dollar slots.

Also, it's going to be very hard to calculate a true expected return on a slot machine with any reasonably large jackpot using a Monte Carlo method (keep playing and calculate the fraction of what you won to what you put in), for the same reason this doesn't work very well in Video Poker - a considerable amount of the expected return is in the jackpot/Royal Flush, which probably won't come up in your play (and if it does, it will skew the value in the opposite direction).

Presumably, multi-reel video slots don't have "virtual" stops, so Monte Carlo is easier, but a lot of the return is in the bonus rounds, and it's very hard to gauge those from casual play.

Thanks ZCore, it's helpful.
3 reel 777 slot vs multiline video slot, same denomination, which one tends to have a higher return?

Every thing I read hints at the reel slots.

You can't really know if they are both generic slot themed. Both can be set higher or lower. Triple stars, Triple butterflies are older 3 real machines that are usually set a little lower hold to get people to play them. Older machines are usually owned outright by the casino and can be set to a lower hold. Most new machines are a 80/20 split between manufacturer and casino so hold is a little higher.

Isn't old 3 reel slots have a lower variance
