Anime about sports that aren't physically demanding, but require fast reaction times and understanding the game to truly excel. Competition vibe is similar and both have the details of the subtle things one can do to improve their ability.
While Baka and Test really only has a quiz show element during the last episode, the entire show over all treasures knowledge above all else just like Fatsest finger.
the difference, baka and test has a different way of "battling w/ knowledge"
In both animes you will have games and hobbies as the main topic. School clubs are the places these game-otakus will meet.
While in D-Frag! the gaming club already exists and shows on a hilarious way their obsessions with everything related to every existing game, in NMSB they want to resurface the quiz club. It's very interesting the fact all the characters in both animes particularly have different interests but an objective in common.
D.Frag! is funnier than NMSB but both really enjoyable.
Phi brain is about puzzles
Nana Maru San Batsu is about quizzes
You might like it, Nana Maru is where you have to be the knowledgeable in a lot of categories where you should know the line, but won't matter if you don't have the first finger on the buzzer. Also they are trying to make a club about quizzes what do you know, they make it. It was interesting and give it a check out, don't like it, it wasn't or isn't for you. Well have fun watching anime.
The characters of both anime have an extensive horizon in the knowledge of literature and other arts. They share this knowledge. In Nana Maru San Batsu answering questions in quizzes, and in Bernard-jou Iwaku. Shiori Kanbayashi discusses with the girlfriend Sawako Machida the facts of the books, light novells, manga, mentioning the related films and anime, from well-known authors.
Hyouka shares with Nana Maru San Batsu the underlying theme of how individuals deal with information. Instead of taking a competitive spin on this, Hyouka takes the detective-genre route. It is still about everyday high schools who take apart questions that don't seem to be like a big deal and try to come up with satisfying answers. This time however, the questions aren't coming from quiz booklets but from the students themselves.
