  • A Bomb Tower upgraded to Cluster Bombs can be helpful due to the high spread out of the explosions, covering multiple paths at once.
  • Bionic Boomer can also help, due to the curves in the paths.
  • Arctic Wind is very helpful if put at the center, especially for Ceramic Bloon rushes, such as round 55.
  • Using Banana Farms to farm money is a good idea.
  • Another tip is not to turn Fast Forward for too much time, since the paths are very short and the player must use Road Spikes constantly.
  • In easy mode, you can look YouTube for win. In hard mode, you can use cash x2.
  • Viral Frost is very helpful if placed in the middle as it can spread the freeze to bloons in all 3 paths.
  • Blade Maelstrom can be placed in the middle and affect all 3 paths at once.
