Friday Fun: Test Your "Eyeballing" Skills
Have you ever put up a picture and just “eyeballed” it instead of using a level? Chances are you stepped back, and realized it was way off, and then had to fix it. That’s the basic idea of this surprisingly fun flash game, which tests your eyeballing skills.
If this game isn’t your style, you can check out GemCraft, our last Friday Fun, or browse through Mysticgeek’s archive of fun stuff.
Playing the Eyeballing Game
The basic idea is using your mouse to find the mid-point in a series of geometric shapes. For instance, in this one you need to move the mouse to the point where all of the lines would normally meet if they were to continue in the same path as the arrows.
In this one, you have to adjust the lines to make a parallelogram…
And here, you need to find the mid-point of the circle.
This is the closest I ever got to being accurate…
Overall, I wasn’t too terribly great at this game – here are my results by category.
At the end they tell you how well you did against the last 10,000 people that played it (completely anonymously)
This is one of those games that you’ll never think is fun until you try. So how well did you do?

Cool! A must play for mathematicians!
great game; accurate to 0.0 units; oh yeah
Parallelogram 4.1 1.4 3.6
Midpoint 3.6 0.0 6.1
Bisect angle 0.5 1.4 0.9
Triangle center 4.0 5.7 2.0
Circle center 3.2 5.1 5.8
Right angle 21.4 16.2 15.5
Convergence 4.0 4.1 3.0
Average error: 5.31 (lower is better)
Apparently the aspect ratio on my monitor is wrong, which causes the rather crappy ‘right angle’ score (which i drew perfectly ;) ) http://woodgears.ca/eyeball/square.html
Sweet! I was in the top 500 last games with an overall of 1.80 :D

@B Banks:
Well you beat me pretty soundly! I shall have to play again =)
This was surprisingly addictive! Love your Friday Fun posts :)
Oh man, I thought I left math behind when I graduated high school. Thanks for the new nightmares!
The right angle is not anywhere near to being 90 degrees. After playing a few times I decided to check it…not a right angle.
OOOPs…I just read the “aspect ratio” information. My mistake. ;-)
great games I get 8.07 ..
@ James…
High School? Heck! My son is doing this in 3rd grade elementary!!! Unbelieveable! Poor kids!!!!!
