Stack your towers

Find a good place to put your first defenses and start the first wave. You can only afford the dart and tack towers at this stage. The stats for each weapon are written on the right side and provide helpful information on how the towers work. Placing your defenses in areas that cover the pathways from multiple angles is best, especially where the tack tower is concerned.

Buy upgrades

As the levels progress, you’ll need to upgrade your existing towers to ensure you can hold back the increasing waves of balloons. Your strongest piece throughout the game will be the dart tower. These can stack anywhere and are very powerful with the piercing darts upgrade, so don’t hold back from stacking these potent monkeys together.

Expand to new defenses

Other balloon types that move faster, contain multiple balloons inside them, and require greater firepower are added into the mix on later levels. The trickiest of all is the black balloon. At this stage, it’s necessary to consider the bomb and ice tower, which you should be able to afford at this point.

Get the super monkey

You should first buy the bomb tower before buying the ice tower, as only bombs can pop frozen balloons. Things can get out of hand quickly as you get into the later game. You must think faster and build more proactively to ensure the balloons don’t break through your defenses. Eventually, you’ll be able to afford the super monkey, which shreds balloons like a machine.

Complete the game

Bloons Tower Defense doesn’t last forever. Once you’ve got all your defenses in the right place, you can coast through until level 50. This is the final round, and completing it ends the game. Congratulations! Now it’s time to play Bloons Tower Defense 2.
