Does the RNG select the stop point of the three wheels indepentently, and then the computer calculate if the resulting symbols is a winner? I think not.
I may be completely out of my mind here, but this is how I think modern slot machines work: You hit the button which fetches a number from the RNG. That number indicates a win or a loss. If it's a win, it also dictates what type of win and for how much (Or a second RNG number dictates that). The computer then stops the wheels on the symbols that match the type and value selected.
Here's the tricky part:
If it's a loser, I REALLY think the computer does NOT have 'random' results displayed. I think the losing wheels will occasionally deliberately show a 'near win'. Not necessarily a near jackpot, but something, anything, that would screw with a player's head and encourage additional play.

Single-line slot machines work by randomly stopping each reel according to probabilities established by the slot maker. Each reel is independent, so the win is determined by the reels, not the other way. My page on slot machines tries to explain it.
Does this mean the RNG stops the wheels WHEN it wants to (i.e. a duration of spin thing), or on a specific symbol?
I.E. Couldn't the jackpot symbol on two wheels be programmed to come up often, but on the third wheel to almost never come up?
DJTeddyBear, I'm afraid you are dead wrong about how slot machines work. I would lay 1000 to 1 on that. I have a box of PAR sheets showing how they are designed. However, I don't want to sidetrack this into another discussion about how slot machines really work. If you want to do that, please start up another thread.
It could be designed to do that, but not programmed.
For an overly simplified example, suppose each reel has 100 stop positions. Reels 1 and 2 both have 10 stops that correspond to the jackpot symbol, but reel 3 only has 1 stop that corresponds to the jackpot symbol. If the reels were designed this way, you would naturally see more near misses where the 1st and 2nd reels have the jackpot symbol, and not the third.
I wouldn't call that "programmed" though, because it is still random, it's just that the probability of a near miss would be greater with that kind of reel stripping.
However, based on John Robison's figure, I would guess that each reel has 368 stops, with only 1 stop per reel corresponding to the jackpot symbol.
Note how there are clusters of the same symbol in a row. For example, stops 60 to 62 on reel 1 all are mapped to a 1 bar symbol. These will all be directed to the same 1 bar symbol on the actual reel. There are exactly 22 groups of like symbols on each reel, which is the standard number of stops on an electro-mechanical three-reel slot machine, known as a "Stepper Slot."
Also note that only stop 45 on reel 1 is mapped to the red 7 symbol. However the blanks above and below it have five positions each. This causes the often seen near miss effect, where the reel stops directly above or below the highest paying symbol.
WHO do slot machines work? OY. I noticed that typo two seconds too late.....
JB, you ARE aware we're talking about a reel machine and not video, right?
Since the physical reel has only about 20 symbols, if it has 100, or 368, 'stops' they are probably not evenly distributed.
If the physical reels are identical, the design can include a random position of which stop table applies to which reel, this way the 'near miss' doesn't show an inordinate number of hits on any specific reel.
Is any of this close to the truth?
Me too! I started my above post half an hour ago!Quote: JB
Edit: Man, I take too long reading, re-reading, and revising my posts. Missed the boat again!
Do the designers randomize the assignment of the table column to the reel so that in the scenario I just described, a loser hitting one or two of the three symbols is evenly distributed among the three reels?
