不親切設計すぎる(It's too unkindly designed.) 日本人の私では答えられない問題ばっかりです。 Most of the questions cannot be answered by Japanese. それに加えて、正解にも関わらず不正解として扱われる物もあります In addition to that, some answers are treated as incorrect despite being correct!
Example: Question→NAME A NBA TEAMS. NBAって何ですか?説明も何もありません What's a "NBA"?There is no explanation.
Question→NAME A PHONE BRAND Answer→DOCOMO→× なんで!?docomoは日本では最も有名な携帯会社です。 Why!? "docomo"is the most famous phone brand in Japan.
Inconsistent and intentionally laggy The answers are usually inconsistent. For example, NYC is accepted but New York is not. Sometimes, United States of America is accepted, but sometimes only USA is.
Also, the typing is intentionally laggy so you would fail and be tempted to play the video.
