February Puzzle

Welcome to Shinteki's Puzzle of the Month, contributed by Ian Tullis. Every month, on the 15th we will put up a new puzzle here for people to test their solving skills. Try it at your leisure just to test yourself, or, if you're the competitive type, see how fast you can solve it and compare yourself against the community at large. When you have solved it, send an email to potm@shinteki.com with subject heading "Puzzle of the Month" that contains your name and the solution. We will add the first 10 solvers' names to that month's leaderboard, in the order that they solved it. Click here to see who has already solved the puzzle, or check out our Previous Puzzles.

Note: The puzzle will be posted sometime on the 15th of each month. If you want to be notified immediately, send an email to potm@shinteki.com with the subject heading "Notify", and we will send you an email every month the minute the puzzle is live.
