    Instructions

    The objective of the game is to get all of the markers to the right side of the game board, using as few cards as possible.

    How to Play

    • Click on the pile to turn over one card. This is your target fraction. Move the markers so that the sum of your moves is a fraction that is less than or equal to the target fraction.

    For example, if the first card turned over is \frac{4}{5} , you could move the fifths marker to  \frac{3}{5} and the tenths marker to \frac{2}{{10}} , because \frac{3}{5} + \frac{2}{{10}} = \frac{3}{5} + \frac{1}{5} = \frac{4}{5} . These moves are shown below.

    • In addition, any of the following moves would also be acceptable:
      • The fifths marker to \frac{4}{5} .
      • The tenths marker to \frac{8}{{10}} , because \frac{8}{{10}} = \frac{4}{5} .
      • The thirds marker to \frac{2}{3} , because \frac{2}{3} < \frac{4}{5} .
      • The fifths marker to  \frac{1}{5} and the tenths marker to \frac{6}{{10}} , because \frac{1}{5} + \frac{6}{{10}} = \frac{1}{5} + \frac{3}{5} = \frac{4}{5} .
      • The halves marker to \frac{1}{2} , the sixths marker to \frac{1}{6} , and the eighths marker to \frac{1}{8} , because \frac{1}{2} + \frac{1}{6} + \frac{1}{8} = \frac{{12}}{{24}} + \frac{4}{{24}} + \frac{3}{{24}} = \frac{{19}}{{24}} < \frac{4}{5} .
    • There are many other moves that would also be acceptable, as long as the sum of the moves is less than or equal to 4/5.
    • When you have finished your move(s), click on the pile to get a new card.
