I got this puzzle off the internet. I DID NOT MAKE IT UP. The black lines are "bones". Click one to take it out. Click it again to put it back in. Click on all the bones and look at the variables to see which bone is which. The Puzzle: Fifteen bones of ancient men, Take back six but still leave ten. It IS possible! Here's a hint: There's more than one way to read the bones. I also got the hint off the Internet.
