That's right, puzzles! That's what perplexus.info is all about. We will try to be posting new ones on the regular basis, so check back often. And if you have one or two to contribute, don't be shy! See how others do against that "impossible" problem your teacher/proffessor posed for you. If you have a solution - post it, we promise not to give it away right away!
So create yourself an account, and go browse the site. Leave comments, suggestes solutions, or just an explanation why someone else's solution is so wrong, it can't get no wronger.
This site is still in active development, which means new features will be added as we go along. Think we're missing something? Let us know!
