About 15 minutes into my last FLL-JFK flight (on an ex-Song aircraft), the Delta FA made an announcement that "the seatback screens are TOUCH screens and it is not necessary to punch them to play the games".

Only after I exited the aircraft and met up with my husband (our parties were split; I was in 3C and he was in 17C) did I find out it was he who complained to the FA about the person behind him who was playing the trivia game .
