I have just reached Rank 180 and got the Room 20 badge. There are two more room badges to go 21 and 22. I wondering if anyone has them yet. I think the room 21 badge is at 195 but can't find any mention of what rank you need to be for room 22 badge. Never-ending game this one lol. Although I now have most of the icons to 1000.
Maybe C~M will know - I'm sure he has all the badges already.
