Choose your level: The first step is to choose the level you want to play. Usually, tower defense games offer a variety of levels with increasing difficulty, so it's best to start with an easier one if you're a beginner.

Set up your defenses: Once you have chosen your level, you need to set up your defenses. In tower defense games, you usually have a set amount of money or resources to spend on different types of towers, each with unique abilities to help you defend against waves of enemies. You can select and place towers in strategic locations to maximize their effectiveness against the oncoming enemies.

Monitor the progress: As you start playing, waves of enemies will start advancing towards your base. You need to keep an eye on their progress and adjust your strategy accordingly. Some enemies may be more vulnerable to certain types of towers, so you need to choose your defenses carefully.
