For stopping the yellow gear, take the left green gear put it behind the right. Then take the yellow gear and move it away. You DO NOT have to put it on the word stop just away from the green gears. For the continue section, type out CONTINUE using the changing buttons and then tap the button that pops up. Please read through other reviews before posting a question as many of them have already been answered. Great game, very challenging to be a creative thinker.
