The computer mastermind has chosen a secret code. Can you crack the code before you run out of guesses?

Guess the Code Free HD is the best codebreaker game for the iPad. Your iPad chooses a sequence of colors and you must try to guess the sequence within a specific number of guesses.

Guess the Code Free HD includes a host of exciting features, including:

* Great graphics and exciting sound effects
* Configurable difficulty levels
* "Use Letters" mode for colorblind players
* Automatic save when you exit the app or receive a phone call

If you are a fan of Mastermind, Bulls and Cows, or Vault Breaker, this is the game for you!

Guess the Code Free HD is supported by unobtrusive banner advertisements.


Please Note: The result pegs do not correspond directly to the guess pegs. The result pegs tell you the number of guess pegs that are in the right position or are the right color, but not which ones. The code does not change over the course of the game and it is definitely possible to figure out the code in the number of guesses allotted.

Not bad

I'd like it to rotate. It's vertically fixed and that's annoying. Also, traditionally, the old mastermind/guess the color games allowed multiple pegs of one color. It was more challenging that way. Still, pretty fun and I like being able to leave blanks. Nice.

Similar to mastermind

But better. Options to add letters to colors, choose blanks or not, repeats or not, and 3 levels of play. And you don't have to worry about "partner" scoring incorrectly!!! A big bonus imho. Plus it's free!

If you like mastermind you should REALLY like this game. No time constraints, don't have to rush. Take all the time you want to solve in the fewest moves possible (besides blind luck).

Ok, so you can't do the dishes while you wait for the other person to take their turn. And share conversation. But Great for impatient players like me.

Love it!

I stumbled across this game and didn't really know what it was when I downloaded it. Then I realized it was just like the old game of Mastermind I played when
I was younger, but with more options to customize for skill level. I play it all the time now. Great way to exercise the brain and increase the difficulty level as my skill improves.
