If this is true, I assume the effect isn't significant enough to overcome the house advantage.

Perhaps some of you living in the U.S. are playing the Safeway/Albertsons/Vons/etc. Monopoly game
, which runs from Feb 3 to May 3. (For those not playing, it's a promotion in which you receive game pieces when you shop at these stores, and if you get the right combination of pieces you win various prizes).
Those playing might be interested in the experience of the "Slot Sisters"
who committed themselves BIG TIME to the game when it ran last year.
By making mass purchases of Ramen noodles, they managed to acquire 42,000 game tickets. They also toured through 6 states, driving close to 3000 miles, because they thought that getting tickets in different locations would increase their chances of winning.
Their final grand total of winnings was $365 in gift cards and $800 in free groceries. Not a great return on investment. As they note, it's "not a game for people on a food budget."
And yet they promised that they'll be playing again this year.
