I programmed the puzzle from the math club PROMPT There are 12 identical marbles. All of them weigh the same except one, which could be either heavier or lighter than the others. You have 3 uses of the balance scale to find the odd marble and determine whether it is heavier or lighter. CONTROLS - Click a marble to relocate it - Choose left, right, or put it back on the shelf - The scale holds up to 6 marbles on each side - When ready, press "Weigh" to activate the scale - Click a marble after weighing to flag it - One click: Green flag - Two clicks: Red flag - Three clicks: No flag Press the green flag in the upper left corner at any time to restart. WATCH OUT - The odd marble is randomized every game - Heavier or lighter is randomized every game - Marble sounds are random. They don't indicate weight - The numbered marbles that you place on the scale appear at the edges of the screen. The marbles on the scale are just decoration
