The main purpose is to create a game based on some significant mathematical content. Depending on this, the tool is created. As you can observe, it can be used in middle school level as an estimation tool for an approximate degree of an angle and its relations with the length of the line segment in front of this angle. Moreover, this cannonball game paves a way for internalizing and practicing some points of the trigonometry concept in high school level. In detail, it can be applied for explaining the position of sinQ through a projectile motion.
