how many levels are there and are we getting mor different areas and animals in Majhong Sanctuary?

There is currently 975 Levels. And there’s no limit to how many they will or can produce…they release (or at least have been recently)  25 new levels every couple months.

Nobody knows if they will add a 3rd biome with more animals. Hopefully Pogo Sconnie will address it in a future Construction Zone post.
