How To Play
You will be presented with a sequence of blocks that will appear at random positions and of random color. You are looking for a repeated display of either position or color that occurs currently and 2 turns prior. When the current position matches (the position 2 turns prior), press the position button. Similarly, when the current color matches (the color shown 2 turns prior), press the color button. At the end of 40 turns the game will end and display your results.
