The rules our teacher taught us are as follows: The game requires at least one deck of playing cards, depending on the number of players, with all jokers removed. At the start, each player is dealt 7 cards. After dealing, flip the top card from the deck and place it aside. During each player's turn, they must perform the following actions: Choose to take the top card from the face-down deck or take any number of cards from the face-up discard pile. When taking cards from the discard pile, you must use the bottommost card you picked up during this turn according to condition 2 below. (Cannot keep it in hand or discard it)...
