Mooble is a kind of mastermind with marbles. In Mooble you are told that you guessed colours right and whether there are any marbles in the right position, but not which ones are right and which ones aren't.<br/>
A blue dot indicates a correct colour in the wrong position, a white dot a correct colour in the correct position. But which marbles do the dots refer to? Can you figure it out?
Use the mouse. Press shift and click to switch a marble back one colour.
