Winseer:
Play Fruit Machines in Pubs, buy a single drink, and leave it on top of the machine for over an hour. (quit slot machines shortly after Gordon Brown abolished Betting Duty of 10%, thereby making Dogs and Horses more viable to bet on, replacing that bad habit playing rigged machines that always seem to pay out the cleaner, and never people like me that played them for hours at a time)
I used to be an AWP (amusement with prizes, or fruit machine) service engineer and believe me they don’t ever consistently pay out to anybody, except the owner. If you ever see a service engineer working on a slot machine, ask him if he ever puts his own money into one on a night down the pub, he’ll laugh at you.
Among players, there is more “kiddology” about slot machines than any other form of gambling, the simple fact is that every event, or play, on a slot machine is totally independent of anything that has happened in the past, a slot machine is simply a quasi random number generator whereby the reels display the numbers pre-selected by the computer in pictorial form and any apparent run of good or bad luck is simply down to the laws of chance.
The biggest revenue earners in Las Vegas are the slots, they make more profit for the casinos than all of the table games put together. If you look at Las Vegas as a thing, that opulence was all built on player losses, not player winnings.
