Yeah, the eyeballing game may look like middle school math at a glance, but don't let first impressions deceive you -- this is one absolutely wonderful way to waste five or ten minutes.

The challenge: Cut lines in half, find the center of shapes, create right angles and perform other simple geometric tasks ... no ruler allowed. When you're done, compare your eyeballing skills to those of other gamers. And don't feel bad if you're nowhere near the top score. We landed ... well, let's just say we're not planning to quit our day jobs.

Also on Lemondrop: Lots, lots more mindless fun. Click through the gallery below to see some of our other favorites.
