Mastermind Solver is a free and easy to use Mastermind game solver written in the Java programming language.

How to play:
· Think of any four digit number, where each digit runs from 1 to 7. We will try the number 6714 in this example.
· After the design has been loaded, click the 'Start/Count' switch once to close the switch whichs wakes the microcontroller up from its power-down mode. Click the switch again to open the switch.
· Wait until the microcontroller has calculated its first guess (6773) for your numbers. Depending on the speed of your computer, this can take a while - less than a second on my Athlon.
· Check whether and how many digits in the computers guess are correct.
· Press the 'Start/Count' button twice to increment the number of correct digits at the right position. As the count starts at zero, we have to press the 'Start/Count' switch six times (0-on, 0-off, 1-on, 1-off, 2-on, 2-off).
· Activate and release the 'Enter' switch to tell the computer about the correct digits.
· Now activate/release the 'Start/Count' switch for any digits that are in your number, but at a differnent position. In our example, there are none, so we skip over this step.
· Activate and release the 'Enter' switch. The microcontroller will now check your input and calculates its next guess.
· Repeat the process with step 4 until the computer has got the right result. It might also complain about illegal and inconsistent input (display 0.0.0.0).
· Once the computer is sure that it has the right result, it will display a walking pattern on the display decimal point LEDs.
