Everybody's heard the "close enough for government work" axiom before, right? And probably everyone has had the opportunity to eyeball a straight line or the center of a circle sometime in the past. Now you can see just how good you are at eyeballing some simple geometric figures with this Eyeballing Game.
This is fun so give it a try. You have to play through each example 3 times to see your score and how you compare to all the other players across the internet. My best score, so far is 5.90. How well can you eyeball?
