You guys are chumps if you think slots can't be beaten.
About 1992, back in the UK- a friend of mine came up with a system to play a range of fruit machines made by a manufacturer called ACE.
System worked by only accepting wins from one certain feature - gambling up to that feature and collecting or making sure you lost the gamble if a win came by other means or rejecting wins. The wins from this feature did not register in the fruit machines memory (bug) and so the machine went into higher payout cycles as it was under the impression it wasn't paying out at all. After about 30-40 mins of playing like this the machine goes crazy and starts throwing in wins every other spin.
I used to make 600 pounds a day for about 3 months till the engineers changed the chips on all these machines. This has happened on several occasions but to a smaller level and I am sure there are many bugs in fruit machines nowadays too.
Agreed the ad is probably a load of bullshit but it is based on truth - probably selling out of date scams.
