Bloons Tower Defense is the original browser strategy game from Ninja Kiwi that launched the entire Bloons TD series. You place towers along a fixed track, upgrade them between waves, and try to stop every colorful balloon from reaching the exit across 50 rounds. It runs free in any browser with no download or sign-up needed, so you can play it unblocked at school or work on any device.

What is Bloons Tower Defense?

Bloons Tower Defense is a fixed-path tower defense game where balloons (bloons) travel a winding track and your towers shoot them down automatically. You spend money earned from popping bloons to buy new towers and purchase upgrades. Waves grow harder round by round, introducing faster bloons, layered bloons that contain others inside, and the tricky black balloon that standard towers cannot pop. The game ends when you survive all 50 waves or when too many bloons slip through and your lives run out.

Towers and how to place them

Click any tower in the buy panel, then click an open spot beside the track to place it. Click a placed tower to view its upgrades and buy them. Tower stats appear on the right side of the screen so you can compare range, fire rate, and cost before committing.

Wave progression and tricky bloon types

Early waves are slow red bloons you can handle with dart monkeys alone. By the mid-rounds, blue and green bloons appear, moving faster and requiring better coverage. Black bloons show up in the later waves and cannot be popped by ice towers. Frozen bloons can only be popped by the bomb tower, so buy bombs before ice or you will waste money on a combo that does not work. The super monkey becomes affordable around the later rounds and is worth saving for.
