AnQ (pronounced UnK) is a number game. Your iPhone (or iPod Touch) randomly generates a secret four-digit number that you attempt to identify. You have a maximum of nine attempts to do so. After each attempt your device provides you with two pieces of information: 1) the number of digits (out of four) matching the secret number and 2) the number of digits (out of four) in the correct place. This is a fun brain teaser. Your goal is to identify the secret number in the fewest possible attempts. Be creative in developing different strategies and you will be surprised about the alternative ways you can find the unknown number.
