It was enjoyable for the few moments it took to solve, but I’m looking for a bigger challenge. This riddle was extremely simple after you look at it mathematically. I simply took what I knew about the problem, and eliminated most possible combinations instantly. I was left with four possible combinations… three of which would need two fives. So I was left with one possible answer, the correct one… This site is the first site I’m looking at for puzzles and brainteasers, I’ve recently decided it can only benefit me to constantly challenge my mind, and I’ll definitely be taking a closer look at some of the content of this site. If you know a good puzzle like this please send it to me at This e-mail address is being protected from spam bots, you need JavaScript enabled to view it . Unfortunately, I’ll not be checking my email frequently, but I most definitely will check it a couple times a month… that is unless I start receiving puzzles more frequently. (I’m not the biggest fan of riddles, but that is because I’m more interested in the mathematical approached to problem solving… riddles are interesting. I’ll start working more on riddles at a later point in time)
