there are 9 buttons on the screen that you can interact with. the objective of the game is to turn all of the buttons off (gray). however, you can only change the state of the button if the button before it is on and all buttons before that button is off. click a button to turn it on or off. sometimes you may need to click a few times if it doesnt work. if it still doesn't work check if it follows all the rules stated above.
