Eyeballing Game
The user is given 7 tasks. Each involves using estimation to achieve a geometric task. Two samples are: moving a ray so that it is an angle bisector, and moving a vertex of a quadrilateral so that it becomes a parallelogram. The score for each task is based on how close one gets to the correct answer. The starting positions for each task are randomized each time one plays.
