A simple Line Align game for reaction training. Before you is a circle, inside of which one arrow is fixed on the axis, which will move in a circle. A small highlighted sector appears in the circle, on which you must stop the arrow in order to get a point. Gradually, the speed of rotation of the arrow will increase, and the sector will become narrower. The task becomes more difficult, if you do not get to the shaded area, the game will end. The arrow can change direction, and the sector can change location throughout the game. Your best score will be saved so you can improve it in Line Align.
