Google drop-down thing + game Q

The drop-down arrow beside search results, with choices “cached” “similar” “share”, is that a new feature?
I think cached results have been gone for a long time.
whats the name of the game where you put a knife between your fingers on the table as fast as you can/fast?
Answer #1
I think it’s new I haven’t noticed it before (but I might not have seen it because I just noticed it after you mentioned it)
The knife game, pinfinger, nerve, bishop, stabscotch, or five finger fillet (FFF)
