Insane Difficulty is a new difficulty level. It is much harder and scarier than Extreme. Insane tracks have three zones. The first zone is near the beginning of the track. If a Bloon at the first zone is popped you will have one more life. This zone will be on the track as green. There is another zone where you don't get more or less lives (aka normal). It will be yellow on the track. Also another zone near the end when a Bloon crosses the zone, you will lose one life. It will be on the track as red. If a Bloon exits the track, you will lose another life, making two lost lives total if a Bloon leaves the track! The tracks cost between $100 and $200 Monkey Money per attempt.
