A great deal has been written about the honesty of land-based slot machines. A great article by Steve Bourie is titled, "Are Slot Machines Honest?" and originally appeared in the 1999 American Casino Guide. (It may be found online by searching for the title in Google or Yahoo!.) Physical, land-based slot machines have a lot of "variations" (being polite) than can deceive the player. Bear in mind, they're all illegal and do not happen. But read the article, closely. However, online casino slots use an electronic "random number generator" or RNG, operating inside a really large computer program that manages the game graphics, the player accounts of those that join the game, the statistics of every hand played, and much more. The random number generator is hard-coded software instructions that do not change. There is absolutely no "sense switch" (see the Bourie article) that may be flipped to give players worse odds. Regarding control parameters, each usage of the RNG is equivalent to the last use, and will be the exact same as the next use. The numbers will come out randomly, however the pattern of randomness never changes. This is a true good thing about software-based online casino slots. Land-based slot machines may also have payout percentages as little as 83%, which isn't true with online casino slots. In online gaming, each machine has the same winning percentage as another machines. You can see the payout percentages for many online gaming sites, and also you shall see that it rarely drops below 95% - that is, the house makes a 5% profit, on the normal. Actually, most casinos can document that their payout percentages are in the 97% - 98% range. It means that you may spend per hour, gamble your $100 stake about three times, and on an average it shall cost you $7.50. But players do not gamble to be average: the true reward will be the well-paying win. And also the high-paying win is balanced, of course, by a range of players who lose and finance that win. So are learn online slot casino (read this) casino slots fair? Yes, they clearly are. The software that operates the games is tested regularly by independent testing laboratories (look for logos at the bottom of the casino website), and no game is individually controllable to be biased. That is a far cry from the matter with land-based slot machines, appropriately called "one-armed bandits". Players improve odds, they get absolute consistency across all games - but no-one can guarantee a win every time. That's just the nature of gambling, and that's included in the thrill. So the next time you want to play a slot machine, even when there is a land-based casino right next door, you are better advised to go to your computer and play the online casino slots. They can be a far better bet.
