This is one of the trickiest challenges I have ever seen in BTD6!
You truly need a Big Brain to be able to beat this Bloons TD 6 challenge.
How did the creator of this BTD6 challenge even come up with this!?
The following btd6 challenge makes us take on round 55 with only two towers and VERY limited tiers! I am not sure if these BTD6 challenges are even possible!
