Random curiosity/advice: The “average shaddy” eletronic slot machine has a mechanism that will always makes you lose money or give very poor prizes unless the machine is actually full of coins. In this state it will usually rewards you with a significant amounts of coins, but it will never gives you the full prize. The system is quite simple as the coins falls on a “bowl” that has it’s weight detected and define if it’s full in order to allow the electronic lights to stop on your betting choices. Otherwise it’s programmed to make you waste money and even give some of your coins back to trick you into trying again to lose everything. But the average gambler will still feel kinda ok, probably thinking “Damn, not this time…”
This is not being exposed with the intent to encourage the gambling behavior.
You usually have some chances to get some coins when it's close to the end of the day's expedient of the given stabelishment, like bars or similars, because the machine can be filled with coins, but after the place is closed the owner of it will remove the excess of coins from the machine since no client will be there to see that.
You are usually playing to lose. Always.
So, keep this in mind while you people are on vacation somewhere these machines are present.
