Machines that have a lot of "close wins" are not outlawed. I think you just misunderstood me. I was referring to the layouts of the reels and not anything that has to do with odds or the payouts. And not
all slot machines use RNG devices. There are still plenty of pull-handle, mechanical slot machines out there. But that's besides the point.

Do you have any info on legal requirements of slots machines? Links?
I've seen TV programs on Vegas casinos and they showed how they "adjust" the machines so that some are tighter and some are looser. I'm curious to know what "adjustments" would be legal wand what would not.
(Just curious, I'm not often in casinos, and when I am, I only play slots for whatever loose pocket change I may have at the time ... and always walk away with jingleless pockets !! )

but you'll have to look to find the docs, I've seen them before. What can be adjusted is the payout percentages, which does not alter the outcomes of the random spins. They design the machines for certain payout percentages, by the number of picture types on the each virtual reel and by how much you win on certain combinations. In Nevada there are machines set anywhere from 90% to 97% payouts, other states may be different. Nevada's minimum legal requirement is only 75%, so the higher numbers are driven by the competitive market. They also adjust whether they pay a lot of small prizes or a few big prizes too, to add up to the desired payout percentage.
But in all cases the spins are random and all possible reel combinations will come up the same number over time. That's true for all U.S. slots as far as I know.
Programming the machine's computer chip is the only way to "adjust" a slot machine or video poker machine (this is 100% independent of the RNG). This requires contacting the NV Gaming Commission (EVERY TIME). So they can't just adjust them at will. The same goes for adding or removing tables and/or machines on the casino floor. They can't just add an extra machine or table whenever they want.

But LVGambler's point seems to be correct ...
http://en.wikipedia.org/wiki/Slot_machine
The table of probabilities for a specific machine is called the Paytable and Reel Strips sheet, or PARS. The Wizard of Odds revealed the PARS for one commercial slot machine, an original International Gaming Technology Red White and Blue machine. This game, in its original form, is obsolete, so these specific probabilities do not apply. He only published the odds after a fan of his sent him some information provided on a slot machine that was posted on a machine in the Netherlands. The psychology of the machine design is quickly revealed. There are 13 possible payouts ranging from 1:1 to 2,400:1. The 1:1 payout comes every 8 plays. The 5:1 payout comes every 33 plays, whereas the 2:1 payout comes every 600 plays. Most players assume the likelihood increases proportionate to the payout. The one midsize payout that is designed to give the player a thrill is the 80:1 payout. It is programmed to occur an average of once every 219 plays. The 80:1 payout is high enough to create excitement, but not high enough that it makes it likely that the player will take his winnings and abandon the game. More than likely the player began the game with at least 80 times his bet (for instance there are 80 quarters in $20). In contrast the 150:1 payout occurs only on average of once every 6,241 plays. The highest payout of 2,400:1 occurs only on average of once every 643=262,144 plays since the machine has 64 virtual stops. The player who continues to feed the machine is likely to have several midsize payouts, but unlikely to have a large payout. He quits after he is bored or has exhausted his bankroll. [15]
Yes its random, but designed to generate action.
To bring this back to poker, the last time I played a "Joker Poker" machine at a casino was before I understood poker or ever played online. So is the deal of the cards "real" on those machines? I understand that the payouts will be set to favor the house, but are the chances of hitting any particular hand correct?
All video poker machines' cards are "dealt" randomly (via RNG). The amount of money a casino is allowed to "hold" is based on an average. This "average" varies from game to game and from denomination to denomination. As far as video poker machines are concerned, the lower the denomination, the higher the house "hold" is. For example, if you put a $100 bill into a penny machine, the % the house is allowed to "hold" (keep) is much higher than that of a $1 dollar machine. The $5 dollar machines "hold" less than the $1 dollar machines. So, the next time you think you're "saving money" by playing the penny slots, think again. It's like the rake in poker. The higher the rake, the less you'll make in the long run.
