Some New Puzzles on the Website

I have put together some puzzles that either I created, were sent to me or I found on Wikibooks. Some have been discussed here already.

Anyway they are at New Puzzles

Some of them are hard, some easy and some make you go "d'oh!"

You can talk about them here and let me know anything wrong with them before I let general visitors see them!

They're pretty cool! I wonder if I found a problem with the 'where did the extra dollar come from?' problem. At the start it says 2 friends eat, but 3 friends pay... was that a typo or intentional?

I found an extended answer to "Lying about their age" and included it.

I am referring to the non-sequitur between the two paragraphs I quoted. The top paragraph wants us to assume that Brook was the eldest. But in the second paragraph, we find Brook actually younger than Cody.
