Button Madness v2.0

Welcome to the Button Madness puzzle. The main window of the puzzle program is a four by four grid of buttons. When you press one of the buttons some of the buttons will change color from red to gray or from gray to red. The object is to the change all the buttons to gray. The simplest mode of play is to start with all the button in the red state. Once this is mastered an added challenge is to start from a scrambled state. There is also a 'difficult' mode which is harder but, quickly mastered if you understand the simple mode of play. Good Luck!!
