Double Mind is a new concept of color code-breaking, which takes the classic Mastermind game, expands it to the second dimension and adds more ways to play it.
As in the original, you have to guess a secret color code. But rather than being in a single row, the colors are disposed into a grid.
The computer will give you information, in terms of how many right colors in the right position - and how many in the wrong position - there are for each row and each column.
By combining those informations, your brain will be challenged in order to make your next choice of colors closer to the final solution!

Double Mind can be played in three different ways, each one with its own rules:

Classic
Double Mind: Classic is the most similar to the original uni-dimensional Mastermind game: you have to guess the secret combination in a given amount of tentatives - depending on the difficulty level you chose, by placing your colors on an empty grid.
The computer will answer with its right/wrong position information for each tentative.

Swap
As in Classic game, in Double Mind:Swap you have to guess a hidden combination, but you start with all the right colors randomly shuffled in your grid. You play in turns against the computer by swapping colors on the grid, and the computer will do the same with its grid. The first one who guesses wins!

Shift
Double Mind:Shift takes a step further from the other two games by introducing a Rubik-cube style of play: the solution is shown, and your goal is to shift the colors by rows and columns in your grid in order to match it. You play against the computer at the same time, and the first one who matches the colors wins!

With three completely different ways to play, and separate unlockable features for each game, Double Mind is going to challenge your logic skills for a long time!
