Quality Online Slot Guide 6494899323475424543
A whole lot has been written about the honesty of land-based slot machines. A superb article by Steve Bourie is titled, "Are Slot Machines Honest?" and originally appeared in the 1999 American Casino Guide. (It can be found online by searching for the title in Google or Yahoo!.) Physical, land-based slot machines have a great deal of "variations" (being polite) than can deceive the player. Remember, they are all illegal and do not happen. But read the article, closely.
Having said that, learn online slot 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 individuals who join the game, the statistics of every hand played, as well as more. The random number generator is hard-coded software instructions that do not change. There's no "sense switch" (see the Bourie article) that will be flipped to give players worse odds. Regarding control parameters, each usage of the RNG is equivalent to the last use, and can 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 benefit of 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 the additional machines. You may see the payout percentages for many online gaming sites, and you will see that it rarely drops below 95% - that is, the house makes a 5% profit, on the average. In fact, most casinos can document that their payout percentages are within the 97% - 98% range. Therefore you can spend per hour, gamble your $100 stake about 3 times, and on a normal it shall cost you $7.50. But players do not gamble to be average: the true reward is the well-paying win. As well as the well-paying win is balanced, remember, by a number of players who lose and finance that win.
So are online 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 get better odds, they get absolute consistency across all games - but no-one can guarantee a win every time. That is just the nature of gambling, and that is a part of the thrill.
