Friday, the second game in the Friedemann Friese Freitag-Project, is about Robinson Crusoe and Friday (Freitag). You play as Friday and must help Robinson Crusoe survive the island and prepare him to defeat the pirates.

Friday is a solitaire deck-building game in which you optimize your deck of fight cards in order to defeat the hazards of the island and two pirate ships. During a turn the player will attempt to defeat hazard cards by playing fight cards from their deck. If defeated, a hazard will become a fight card and is added to the players deck. If failed the player will lose life tokens but also get the opportunity to remove played cards from their fight deck. Finally the player will use their optimized fight deck to defeat two evil pirate ships allowing Robinson Crusoe to escape the island!
