Bloons TD - Pop Every Balloon Before They Escape

Bloons TD (Bloons Tower Defense) is the classic strategy game where monkeys with darts defend against waves of colorful balloons creeping along a path. Place towers, upgrade them, and counter each bloon type — red balloons are easy, but lead, ceramic, and MOAB layers demand specific towers. Misplace a turret and bloons leak through, costing lives. It is the game that launched an entire tower-defense franchise.

How to Play Bloons TD

• Place towers: Click open spots near the bloon path to deploy dart monkeys, tack shooters, or bombs
• Start rounds: Hit Play to send the next wave — prepare before you launch
• Upgrade: Click a tower and buy pierce, speed, or range upgrades between waves
• Counter bloon types: Lead bloons need bombs or fire; camo bloons need special detection
• Protect lives: You lose when too many bloons reach the end of the track
