To play the game, click on a tile to move to it. The objective is to reach the target without being hit by enemy cannon fire. To clear your path, you can use the shoot button at the bottom of the screen to push cannons and other obstacles out of your way. If you get stuck on the later levels, you can change the direction of your tank without moving it by clicking on a blocked-off square. Use your strategic thinking and problem-solving skills to navigate through the levels and reach the target.
