Counterfeit Coin

Your goal is to identify the counterfeit coin by using the balance to compare coin weights.

You may drag as many coins as desired onto either side of the balance, but the scale is locked until you are ready to weigh your set of coins.

When you Weigh Coins, the scale will either balance (level) or tip to indicate the heavier side.

The Good pan is just for convenience to help track the results of your weighings; you don't have to put all the good coins there.

When you finally identify the counterfeit coin, drag it to the Bad pan, and the computer will let you know how well you have done.
