Bloons Tower Defense 4 Cheats :
Glitch - Place any tower anywhere
by Unregistered Jun 21, 2010
All you have to do is select the tower and move it to a place it can be put on. Right-Click and move it to ANY area on the map and Left-Click where you want it to be put. It will be put anywhere except on top of towers. You may place it on the track or anywhere. I figured this out by myself.
