EDIT: Here's another cap but instead of the preview it's from the aired episode, thanks to simplyiris.
I'm not 100% sure if it's the actual one but it looks like a pretty good chance so I decided to make the thread. If it's not then Mods can delete it. Okay, it's totally Soshified's jenga set! It looks like WGM PD cut the part where they played cause of time restraint, we got our confirmation so it's all good! Go, soshfied! I wonder if Seohyun brought it to her house or if TaeNyHyo brought it since they came carrying a lot of stuff! Never thought I get to actually see them with the Jenga game but it's SNSD who always surprises us and are always using their gifts
