Bloons Insanity is the fourth game in the Bloons Flash puzzle series. As with the previous games, the goal here is to pop all of the balloons in each level with a limited number of darts. Each level includes a number of special balloons, with new ones in this game including rainbow balloons that rise to the sky and lightsaber balloons. Also new to this game is the ability to throw more darts without having to wait for the previous dart to finish its trajectory, something you had to do in the first Bloons game.
Randomno in this run completes every level in this difficult and precise game as fast as possible.
