These Monopoly games come with real money

Passing "Go" and collecting $200 could soon take on a whole new meaning. At least in France, where the maker of Monopoly has secretly added real money to some sets instead of the brightly colored fake bills.

The switcheroo is marking the game's 80th anniversary, and 80 sets will have different combinations of euro notes. The biggest jackpot replaces every single bill with real money totaling 20,580 euros, or $23,268, according to AFP.

Other sets will have far less. Ten will contain 300 euros in smaller bills, and the remaining 69 will have 150 euros each.

Sounds like the French arm of toymaker Hasbro (HAS) is channeling Willy Wonka, but executives said they were inspired by customers. The company polled people to find out what they'd like to see in Monopoly boxes to mark the game's 80th birthday, and about 50 percent preferred cold, hard cash.

An astute observer may be able to ferret out the winning boxes. That's because they have a slight bulge in the packaging because euro notes are larger than the play money. Hasbro says the weight is the same, unless you're measuring with precision scales.

The real-money stunt isn't making its way to U.S. games anytime soon. In its home country, Hasbro is offering a new 80th anniversary edition of the game with a vintage-looking board, money and buildings. The game will also have classic tokens used over the years, including the lantern and the money bag. The game was selling Tuesday on Amazon (AMZN) for $16.
