Puzzle 574: Ripple Play 7

MellowMelon's posts about the current World Puzzle Championship suggest that there are a lot of 21-themed puzzles this year. As such, I have scheduled this puzzle to go up at 21:21. Hahaha, I am so clever.

Cleverer if it had 21 rooms?

Anuraag: You know that mathematical recreational activity where you take an integer, add it to the reversal of its digits, and keep on doing that until you get a palindrome? If you do that starting with 21, you get 33. There are 33 rooms.

Yeah, baby.
