GETTING STARTED

Player 1 turns over three cards from the top of the deck and uses them to form a number with a decimal. She uses black cards as whole numbers and red cards as decimals.
    Example Player 1 draws a black 4, a red 1, and a red 6 to form the number 4.16.
Then Player 1 takes three more cards and forms another number. She adds together the two numbers.
    Example
  • Player 1 draws a red 3, a black 2, and a black 1 to form the number 12.3.
  • She adds 4.16 + 12.3 for a total of 16.46.
Player two takes his turn. He does the same thing.

After this first round, play continues. Both players turn over three new cards per turn. They continue to keep a tally of their scores until one player gets closest to a total of 500 (or 1000) without exceeding it.
