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.
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.
