Word P.I.

On Pi day, I was looking at creative pi ideas, questions and games. I came along a game called Word P.I., which has nothing to do with pi the number. It's basically the game Mastermind, but with five letter words. It is quite intreging. How is it any different from Mastermind? Very. All words guessed must have the following qualities: 5 letters, no repeat letters, is in the dictionary. It's the last rule that makes the game harder. So if you know the word has the letters "e" and "s" you can't just guess "seabc" then "sedfg" and so on to find the rest of the letters. It's fun and challanging. It's a must try in my book.
