Thereís a java game on the web that use to play but I lost the link when my hard disk crashed.
It involves having to find the center of a circle, square, bisect an angle using your mouse. The accuracy of where you place the mouse/point & how long it takes you scored.
You would do about 10 problems in each level and an overall score was generated. Your score was compared to others that had played the game.
The game is very simple, no real graphics, just white background and black lines.
If anyone is familiar with the game and could post a link that would be fabulous!
