The Freitag-Project (Friday Project) is a series of games by designer Friedemann Friese. All of the games were designed exclusively on friday. Some of them share the common theme of Friday. The first game in the series is about the Stock Market and features a rise and crash of a stock market, which happens in the "black friday". The second game in the series is about Robinson Crusoe and his native companion Friday. The third game - Copycat breaks the "friday" theme. It is about politics, and also about borrowing elements from other games.
