You are shown the plane of complex numbers, together with a point in this plane representing a complex number z. And you have only to click (shoot) on the complex plane, at the points representing the (square, cubic, quartic, or quintic) roots of z. You will have a score computed in function of the average precision of your shots.You can also try Complex shoot which asks you to click on an algebraic expression of a complex number.
