Being a computer engineering student, I have had lots of exposure to both hardware and software.  One software project I did was with the Altera DE1 Board using NIOS assembly code.  Our last project in that course was one that was open to any program, so my friend and I decided to do MasterMind.  Although there were many challenges, we finished the project and I have attached the code so those who would like to play mastermind on their DE1 (or DE2) boards.  The DE1 board plays “We are the Champions” by Queen when you win but you will need to know how to incorporate a Wave file in order to make that work.

The instructions are as follows.

Rules:

To start:

1. Key 1 is the store answer key
2. Key 3 is the start key

After started:

1. Switch 2 to 9 are in pairs, each pair represent 1 digit of guess in binary numbers, so the answer is 4 digits (Possible answers include 0,1,2,3)
2. You have 10 guesses until you lose, the red LED will keep count of the number of guesses.
3. Hints will be displayed after each guess.
4. It will also tell you if you’re closer or further from the correct answer.
5. Key 1 to give up.
6. If 1 digit of your guess is the same number and same place as the answer, 1 black hint will be displayed; If 1 digit of your guess is the same number but different place as the answer, 1 white answer will be displayed.
7. When you win, it will tell you.  Then the green LED will tell you how long you took.
8. It will also play “We are the Champions” by Queen.
9. It then waits for the user to either store another code or start the game.
