Next Seven Days is a solitaire card game representing the first week of the new world. With a deck of various events, numbered 1–20, each with a special piece of story and effect, the player must discard some of the cards in order to play the cards they want. Cards must be played in a strict pyramidal form in seven layers, obeying the rules for numbering. The game is played in seven rounds, and if the player manages to create an unbroken line of increasing numbers from round one to seven, the week is complete. Points are awarded for achieving special goals.
