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.

Some definitions for people who don't remember geometry:
Parallelogram = opposite sides must be equal lengths and parallel to each other
Bisect = cut in two equal halves
Equidistant = center of the biggest circle that can fit inside the triangle
The others should be fairly self-explanatory.


My best average so far is a 3.5

Best average 6.7. I played it twice then i got bored.

best i got after a few tries was 3.04 even with 2 5.0's and a 6.8.

sometimes the parallelograms are really easy and sometimes they kill me.


Just got one accurate to 0.0, but screwed up pretty much everything else

straight line and convergences are pretty easy to 0.0 or near there. Circle and equidistant from edge are pretty easy to get under 1.

The right angle is brutal, so are the parallelagrams, sometimes you can't tell how far from 90* it is...

Overall score: 5.86

I got the first equidistant thing perfect first go.

Edit; second attempt; Overall score: 5.86 again.

3.68 is my best, on my third try though

2.80 first try

3.42 on my first go.

am not bothered to do it again

Your inaccuracy by category:

Parallelogram 8.6 2.2 2.2
Midpoint 3.0 2.2 3.6
Bisect angle 0.7 3.6 1.5
Triangle center 5.4 2.4 12.3
Circle center 4.0 6.1 10.8
Right angle 0.2 7.3 0.1
Convergence 5.0 4.1 5.4

Average error: 4.32 (lower is better)

I'm averaging a 1.3. My best has been 0.0 on a converging lines one.
