Welcome to Mastermind, but with numbers! You get ten tries to guess the correct code. Put a code in and hit the check button to see how close you are. A red box means that number doesn't show up at all in the code. A yellow one means that number shows up, but in a different slot. A green one means that number is in the correct place. The keys to change each of the numbers are posted above the boxes. The first makes it go up, the second makes it go down. For example, the first one goes up when you press w, and down when you press s.
