This applet plays MasterMind.   See how quickly it can find your secret selection.

alt="Not running the applet, sorry." <Applet> tag ignored"
A row of discs shows the available colors.
Choose a set of four, and remember it or write it down.
Repeat of colors is allowed.

Click PLAY to start the applet trying to guess your selection.
When a guess of four appears, you inform the applet of its accuracy by clicking some or all of the four small squares at the right.


Click once to make a square black, indicating a disc of the right color in the right position.

Click again to make the square white, indicating a disc of the right color, but in the wrong position.

A third click of a square returns it to empty, in case corrections are needed.

Leave open one square for each disc which is missing from the selection.
The squares are NOT positional - choose any of them for any of the four positions in the guess.
When you are finished clicking the squares (anywhere from zero to four might be filled), click READY to see the next guess.

A short cut to confirming all four correct is the "That's it" button.

To try another selection, click PLAY.
If no more guesses are possible, "I give up" is displayed. This means that you have made an error in giving the results.
