To Play

• Shuffle the deck and place the cards in a pile, face down. Place a playing piece just off the board near square 1 for each player, and decide who goes first. Draw a card and move as indicated. The next player draws the next card and moves as directed. The winner is the first person to get to 60, or the person who lands on the highest number after a predetermined time limit is reached.

Other Rules

• Do not move if you are told to go to a square already occupied or a square not on the board (0, negative integers, or numbers larger than 60).
• WHEN DIVIDING, DISREGARD THE REMAINDER.
