iPhone version of the classic Mastermind color code sequence guessing game. One player picks a secret color code sequence that the other tries to guess, based on certain clues from the code maker.

This app allows you to play either as the code breaker (you deduce a code chosen by the app) or as the code maker (the app guesses a code that you choose, based on the clues you give). It also includes a clue generator, that aids in giving correct clues when playing as code maker (either against the machine or another human).

It features a simple, intuitive interface using familiar controls. It includes a "Get Started" tab that provides pop-up instructions for each interface element in each of the three play modes.
