How the game works

The best way to figure out how the game works is to simply play it.

The game works by showing you a series of geometries that need to be adjusted a little bit to make them right. A square highlights the point that needs to be moved or adjusted. Use the mouse to drag the blue square or arrowhead where you feel it is ‘right’. Once you let go of the mouse, the computer evaluates your move, so don’t let up on the mouse button until you are sure. The ‘correct’ geometry is also shown in green, so you can see where you went wrong.

You will be presented with each challenge three times. The table to the right shows how you did on each challenge each time.

Once you have done each challenge three times, the computer tallies up your average error. The lower your average error, the better. A theoretically perfect score would be zero. The error is measured in pixels, and in degrees times two for the bisection and right angle problems.

The computer keeps a best scores table, one for everybody, and one for just your computer. If your score is better (lower) than the bottom score on either list, you get to enter your name in the best scores.

The best scores only show scores in the last 500 plays. So your scores will fall off the best scores list after 500 more games have been played, even if nobody beats your score. This will allow mere mortals in the best scores list as well. The game also keeps track of the best of the last 10,000 plays on the best scores page
