Bloons Tower Defense 4 is a tower defense game in which you deploy monkeys with darts to pop balloons. The game is a spin-off from the Bloons game series and the sequel to Bloons Tower Defense 3.


The game is a classic type of tower defense game in which the enemies follow a predetermined path on each level. All enemies in the BTD games are balloons called Bloons. The basic tower, called a Dart Monkey, is a monkey throwing darts at the balloons, similar to the original Bloons game series. The other towers have to be unlocked by popping a certain number of Bloons. There are 16 types of towers and all of them can be upgraded.

There are six levels and each of them can be played in 5 different game modes. The first three game modes (Easy, Medium, and Hard) differ only in difficulty. The Sandbox mode lets you customize your game. Apocalypse mode is an endurance mode with endless waves of Bloons. The game's level editor is only available on the official Ninjakiwi site.

You can purchase additional tracks and upgrades by spending Kreds. You can also spend Kreds to purchase lives and cash on a level during gameplay.
