| In this game you will move 2 markers along 2 number lines. The object is to move either marker to a point above zero. |
| You can turn over cards by clicking on the deck. |
| The fraction on the card, or its equivalent, should be subtracted from the number below the marker to determine the distance the marker can be moved. |
| Only one marker can be moved for each fraction, and the marker must be moved to a point which is above one of the numbers on a line. |
| If you can move a marker to one of the points above zero without missing more than 2 moves, you win the game. |
