What Is Considered an Advantage Slot Machine? Please Name Some of Them.

What is considered an advantage slot machine? Please name some of them.

Machines are considered advantage slots if you can play them at optimal times, meaning when they're programmed to pay out.

Spins on these machines aren't independent events, like most regular slots. Instead, they "build" from spin to spin and don't reset back to scratch after each one. The build can involve more numbers, coins, bubbles, wild symbols, anything that indicates a change in the probability of hitting a bonus or jackpot. (If you'd like an excellent primer on persistence/variable-state games, you can read one by slot expert Buddy Frank.)

These games are introduced to the casino floor at a dizzying pace, but many of them play off the principles of a few. For example, in his book Breaking the Slot Code, Ben Rosenthal recommends Scarab as the game to learn if you want to learn just one; it will help you pick up on many other games that follow the same mechanics.

So that's one name to know. Breaking the Slot Code has 25 main games, but several offshoots, such as Captain Riches, Tiki Fortune, and Mine Blast come from Ultimate Choice Jackpots. Then you have Wu Dragon that's a lot like Star Goddess; Regal Riches and Prosperity Pearly; Wolf Run Eclipse and Cats Wild Serengeti; Wolf Peak, Cat Peak, and Fu Ren Wu; and the like -- 13 more names for you.

The website associated with Breaking the Slot Code, SlotSlayers.com, has at this moment (it changes frequently) 180 advantage-slot games. You can see five of them for free: Dancing Drums, Golden Egypt Grand, Magic of the Nile, Zodiac Dragon, and Lucky Lemmings (five more names for you). All you have to do is click the link above to the home page, click on Membership/Shop--Why Join, and scroll down to the games. You'll get an excellent preview of what the book looks like, with instructions and photos, and what the website will show you, with instructions and photos, plus videos of all the the game.

The one to look at, in our opinion, is Zodiac Dragon (and Lion). This game has two others, Lucha Kitty and Sumo Kitty, that share clear similarities, Wild Pirates and Guardians of Egypt that are somewhat related, and Ocean Magic, Ocean Magic Grand, and Dragon Sphere that share an element with the “zodiac wheel.” That's another nine names for you -- a total of 28 advantage-slot games in this answer.

We hope those will get you started.

Please clarify

The answer seems a little ambiguous, so let me ask the question in a different way:  Are there slots that a knowledgeable player can exploit for a positive expectation?  And if so, how do we know, given that par sheets are not made available to the public?

Short answer: you don't know

In order to evaluate whether a machine is in a positive state, you MUST know two things: one, the inherent payback of the machine, two, the frequency of the bonus (in its current state). You need the former to calculate the cost of hitting the bonus on a per-spin basis and the latter to know how many spins it should take (average or median). But there's no way to know either; all anybody has is trial and error, with a far too small sample size. It is certainly possible to determine that a given machine's return, in a given state, is better than normal. But can a player determine, beyond any doubt, as in, mathematically, whether that return now exceeds 100%?

No.

"Are there slots that a knowledgeable player can exploit for a positive expectation?" Most likely, yes.

"How do we know?"
How do some people know which ones? The obvious answer is, "Trial and error." There are other possibilities, including a PAR sheet being leaked.
How can you find one? That's like going up to a magician and asking them how a trick is done. The people who know usually don't want to reveal their information, out of some combination of fear that (a) they won't be able to get to these machines themselves, and (b) the casinos/manufacturers will "fix the problem."
