Some towers are good at detecting camo bloons, while others are good at popping lead bloons. Some towers have special abilities that can boost your defense or offense, such as the monkey village that can increase the range and power of nearby towers, or the banana farm that can generate extra money.

  • Know your bloons: Learn the types and behaviors of each bloon and how to counter them. For example, some bloons are fast and agile, while others are slow and bulky. Some bloons are immune to certain attacks, while others are vulnerable to them. Some bloons can spawn more bloons when popped, while others can explode or freeze your towers.

Tips for Winning

Here are some tips that can help you win more games in this game

  • Start with cheap and efficient towers: At the beginning of the game, you want to save money and build towers that can pop a lot of bloons with low cost. For example, dart monkeys, tack shooters, and boomerang throwers are good choices for early game defense.

  • Upgrade your towers wisely: As the game progresses, you want to upgrade your towers to make them more powerful and versatile. However, you don’t want to spend too much money on upgrades that are not necessary or useful. For example, you don’t need to upgrade your dart monkey to shoot explosive darts if there are no lead bloons in the round. You also don’t need to upgrade your tack shooter to shoot faster if there are no fast bloons in the round. You should upgrade your towers according to the type and number of bloons you are facing.

  • Mix and match your towers: To pop all kinds of bloons effectively, you need to use a variety of towers that complement each other. For example, you can use a ninja monkey to detect and pop camo bloons, a glue gunner to slow down and weaken bloons, and a bomb shooter to deal splash damage and pop lead bloons. You can also use a monkey village to enhance the performance of your towers, or a super monkey to deal massive damage to any bloon.

  • Use special abilities: Some towers have special abilities that can be activated by clicking or tapping on them. These abilities can give you a huge advantage in certain situations, such as clearing a large wave of bloons, destroying a MOAB, or boosting your income. However, these abilities have a cooldown time, so you need to use them wisely and sparingly.

  • Have fun: The most important tip for winning is to have fun and enjoy the game.  that offers endless possibilities and challenges for players of all ages and skill levels. You can experiment with different towers, upgrades, modes, tracks, and strategies to find your own style and preference. You can also play with your friends or other players online to share your experience and learn from each other.
