Monopoly is the No. 1 board game in France, selling around 500,000 sets per year, and as a hat-tip to its fans, manufacturer Hasbro is now literally paying it forward by releasing units with real money in honor of the game’s 80th birthday.

In some sort of Willy Wonka and the Chocolate Factory-esque fever dream (or a marketing ploy everyone can get behind), 80 of the 30,000 Monopoly games newly available in France today will have straight-up euros inside. Sixty-nine boxes will contain 150 euros ($170), 10 will have 300 euros ($340), and one lucky shopper will make serious bank with 20,580 euros ($23,349) in cash.

The gimmick came about after execs at the company were trying to come up with a way to celebrate the game’s birthday. They decided to run a survey about fantasy Monopoly scenarios and, unsurprisingly, it all came down to money. “We were looking for something special for this birthday and found out that the majority of French people playing dreamed of, one day, finding real money when they opened the box,” explained Florence Gaillard of Hasbro France.

Don’t fret, die-hard gamers, they also include a full set of Monopoly money.
