Bloonarius Prime rounds in alternate path

Bloonarius Prime has an alternate path that only opens up during prime numbered rounds. This guide is to let you know what fixed rounds will go to this alternate path so that you can better prepare yourself in CHIMPS (or other gamemodes).

TLDR (and other quick info):

Easy: 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37
Normal: 41, 43, 47, 53, 59
Hard: 61, 67, 71, 73, 79
Impoppable/CHIMPS: 83, 89, 97

Freeplay: 101, 103, 107, 109, 113, 127, 131, 137, 139, 163, 263

Notable rounds on this alt. path (does not apply to ABR):
37 - First round with camo bloons and lead bloons
43 - First round with ceramics
53 - First MOAB blimp round
59 - First round with camo lead bloons
73 - First BFB blimp round
97 - First ZOMG blimp round

How this map works:

The map has two separate tracks. The right track is only used in specific rounds while the left track is used in every other case.

The way that bloons end up on the right track is through a "muddy puddle"(heh) that becomes a portal. The portal will only open up in prime* numbered tracks.

*Prime - A special whole number where if you list the factors that multiply into that number, the list will only contain 1 and the number itself.
example:
7 is prime because its factors are: 1, 7
15 is not prime because its factors are: 1, 3, 5, 15

Note: 1 is not considered a prime for complicated reasons that don't need to be talked about here, just remember that it isn't prime.

Main rounds on the right side (r1-100)

Freeplay rounds on the right side (101+):

101 - 450 Purples, 50 Fortified Ceramics, 10 Fortified MOABs
103 - 198 Purples, 100 MOABs, 50 Fortified MOABs, 10 Fortified ZOMGs

163 - Random amounts of all variants of leads and ceramics
263 - Random amounts of MOABs, Fortified MOABs and DDTs

Alternate Bloons rounds - Still makes all rounds past 100 completely random.

For all other rounds in freeplay, they are completely random. However, if you still want a list of prime numbers for challenges or some other usage, here's a link to a web page of that list: https://www.mathsisfun.com/numbers/prime-numbers-to-10k.html

Small note: Fortified BADs in the random freeplay rounds will only appear in rounds 201+

I feel so dumb not realizing the alternate tracks were on prime number rounds

I mainly made the image for myself but I decided to create a guide so that others could use it lol
