Endless waves of colorful baloons are marching toward your exit, and only your towers stand between them and the end of your lives counter. In Bloons Tower Defense 4, you plant dart monkeys, tack shooters, and bomb towers along a twisting track, then watch them pop everything that floats past. You click to place each tower, click again to pop open its upgrade menu, and spend your hard-earned cash to push attack sped, range, and pierce higher before the next wave hits. Layered bloons get nasty fast, so you have to read each round and patch the gaps before lead and camo balloons slip through. Ready to defend the line?
How to Play & Controls
- Place towers: Mouse click on the track to drop a selected tower.

Tips & Tricks
- Open with a couple of cheap dart monkeys near the entrance to bank money early.
- Rush a Ninja Monkey or Super Monkey before the camo and lead rounds arive.
