Evil green monsters have appeared in the magic kingdom, destroying everything in their path. In the game Cannon Egg you will go to war with them. In front of you on the screen on the playing field there will be a structure in which monsters have settled. There will be a cannon at a certain distance from it. It will be charged with an egg. Using the control keys, you can move the implement to the right or left. Having set up the cannon, you will have to calculate the trajectory of the shot and the readiness to make it. If your sight is accurate, then the egg, having flown a given distance, will hit one of the monsters. Thus, you will destroy the enemy and get points for it.
