The Machinist

 is the 24th level in Bloons Insanity. Both precision and timing is very important in this level.

Strategy
Try to pop the top Lightsaber Bloon first, which should lead to all the tacks passing to pop every bloon on the right side. Before the Triple Dart Bloon arrives, use the boomerang to pop all of the lower bloons, then use the last Triple Darts to hit the ones on the left. Be sure to use little power and slightly upwards with them.
