Anyone know how to get out of this? The box was there when I placed the last balloon, then the elf moved over to block me in.
Look half way down for support option.
On your game screen, choose the Settings cog (Mobile, upper left corner; PC, upper right corner)
If you're on an iOS device, try the SUPPORT link, but if you don't see any categories below the search box, then you'll need to email them.
News for that are here
They are working on a fix.
