Do rooms combine from top to bottom in Fallout Shelter?
Nope, rooms in Fallout Shelter only combine side by side, not top to bottom. Think of it like expanding horizontally, not vertically. So, if you want a bigger, more efficient room, place two or three of the same type next to each other on the same floor.

Big no-no, my friend. Rooms go wide, not tall. You gotta stick 'em side by side for them to merge.
Absolutely not. I tried doing that when I first started and was confused why my rooms wouldn鈥檛 combine. They only combine when placed next to each other, horizontally.
