How can this guy claim to beat slots?

[RolledAces]

LOL, funny how the guy who hit $4,000 on a $1 ten times pay machine happens to just be in HIS GARAGE! Look at the background, of course when u buy a slot machine, u can fix the payout to the point where EVERY PULL yeilds a jackpot! Also, there is this program called "Photoshop" nowadays where the person who is posting this ebay item seemed to of "photoshoped" 4,000 credits on the first slot reel....
