The game works like this. Each round, the computer adds a few random weights to the right side of the scale.
Using the mouse, you need to inflate up to three weights on the left side of the scale to balance out the total weight on the right side of the scale.
Simply hold down and release the left mouse button to inflate a weight.
You "win" a round by adding weight on the left side of the scale that comes within 5 pounds or less of the weight on the right side of the scale.
This is a great puzzle game for improving attention and cognitive control. Have fun!
