I thoroughly enjoyed playing this game with my students in class! It was a great way to practice using adverbs of frequency! As you suggested, we did this as a classroom activity where each student wrote down 5 "actions" on a piece of paper and then we took turns pulling a paper and asking "How often do you ____ in the summer/winter?" I then took it one step further and asked my students to create posters in their groups of the questions and answers they came up with. Here is the result! Thanks for this great activity, we loved it!
