Bloons Tower Defense is a tower defense game where the goal is to keep those pesky balloons from flying out of your range. You'll have to pop them before you lose sight of them using darts, pins, and even bombs. You can plan your strategy before each wave, so make sure to use your time and money wisely.
In the game, players attempt to prevent Bloons (in-game name for balloons) from reaching the end of a set course by placing towers or road items along it that can pop the bloons in a variety of ways, typically by utilizing the power of monkeys. Some towers can stall the bloons and give the other towers more time to pop them by freezing and gluing the bloons. Money is gained by popping bloons, completing rounds, and collecting bananas from existing banana farms which can be spent on new towers, upgrades for existing ones, or temporary items such as exploding pineapples and road spikes.
Click/tap the towers you'd like to build and click/tap on the area you want to put them. You can also click/tap the towers you've built to check any upgrades you can buy.
