In the casual game TRZ Cannon, players must calculate the force and range needed to fire cannonballs into the goal in order to win. Run a targeting test. From above, your foes will pelt your city with fire, destroying it. To save your city, you must take whatever action is necessary. Shooting the cannonballs and making sure they land in the basket is your objective. Use the left mouse button to change the strength and arc of your shot. To produce a flawless shot, you must properly measure the distance. The early stages are easier overall, making it simpler to hit the objective. You will need to strike moving targets and progressively more challenging obstacles as you progress through the game to become a better marksman.
