No doubt similar stunts are pulled elsewhere. Many gamblers are easy meat for exploitation.
In the earlier days of Atlantic City, New Jersey there was a similar case that I do believer was either addressed at the state level or the federal levels, not sure. But it centered around the payouts which the casinos advertised that they pay back. I don't remember what figure was mandated and what was advertised by the casinos. But slot machines can all be 100% adjusted, set and calculated what to pay out, not when or whom to pay it out to, which was substantiated by the government, at least here in the USA.
But paying out $4.00 on a $10.00 play, with the bells and whistlers and 'winner' declared, is just a trick that has been around. There was some discovery prior of people exposing the machines where there was less 'key' symbols on the wheels towards the right side that stop last than on the other reels, which was another one of their tricks.
Same thing with the lotto machines these days, bells and whistlers for a $1.00 to $5.00 ticket with the announcement from the machine, "Whoo Whoo-Your AWinner"! Paying less than what you paid for a lottery ticket and announcing your a winner.
We know that the Casinos have manually spun roulette wheels with an R N G outcome, many times they have been asked what is the percentage payouts on Rapid Roulette and they will not tell you. Down here the Casinos do not have to display the winning percentage .I don't know about they rest of the world.
You ask a pit boss and they all give you the same answer ,we don't know. They don't deny it, but gee they entice you to play the Rapid down here.
There is plenty on the www showing those wheels just go searching and you will find it, I say this because many do not believe it .
cheers
