I found this interesting, and since nobody else mentioned it, I thought I'd share.
According to a brief mention in last week's TVG, out of 35 countries where DoND is produced, two players have won the show's top prize -- though there's a pretty huge difference in their winnings. A player in Italy won 500,000 euros (about $600K), and a player in Mexico won a million pesos (less than $100K). The article said that the biggest cash win was in Holland, where the grand prize is five million euros ($6M US) and a player made a deal for 1.5 million ($1.8M US).
Is the game in The Netherlands routinely played for five million euros? That seems like an unusually large prize for European TV.
BTW, turns out this is the 111,111th post in our forum's history. Couldn't be prouder.
