You will drive the ball and negotiate the hills in Slope Racing 3D using both your mouse and keyboard. Steering the ball left and right correspondingly, use the A/Left Arrow and D/Right Arrow keys. Using your mouse and Left Mouse Button will let you choose and activate power-ups that show on the right side of the screen. Rolling the ball as far down the hill as you can will help you to gather jewels and steer clear of challenges along the slope way.
