    So Much Fun for Game Night!

    This game is such a fun addition to family game night! The questions are interesting, and there were plenty of moments where we laughed and said, “I should have known that!” It’s easy to learn, keeps everyone engaged, and sparks some friendly competition. Definitely a great game to play with family and friends.

    GREAT FOR GAME-NIGHT for Trivial enthusiasts

    “Should Have Known That!” is an intellectually stimulating trivia game that transcends the ordinary, making it a standout in the realm of knowledge-based entertainment. This game captivates with its unique approach, challenging players not just to recall facts but to delve into the depths of “things you oughta know.”As a trivia enthusiast, I appreciate the thoughtfulness behind the questions. They require a nuanced understanding of a wide array of topics, appealing to the curious mind that craves both breadth and depth of knowledge. It’s a refreshing departure from standard trivia fare, elevat

    Pride goes before the point reduction!

    okay so this is really fun and if you have people who are super competitive, this can get super intense. It is also a convo starter because some of the questions are like what in the world. Some can say it is "unfair" because the questions can be super easy or super difficult, but in the end we have a good laugh. There's a lot of competition and some egos can clash but they still get over it if you try to bend the rules a little. As in taking half the points if they are close enough, or giving a point back, etc etc. Def fun for game night with people who think they know it all. hahah

    Fun trivia game for a family

    Its nice fun but many questions are strange in that they cannot be easily answered. Nice for general trivia.

    Great family friendly game for really all ages.

    As simple as this game is, it's super fun to play with friends and family. Either play as individuals or as teams. We played boys vers girls, I won't tell you who one, but when you don't know an answer you will likely say duh I should have known that. It's a solid card game with many ways to play and is fully enjoyable. Family and friends as me to bring it to gathering in hopes we can play it again. I wish Amazon would sponcer my reviews, because I will thorough and unbias. And I love tech and games, but until I get the invite I'll continue giving my unbias opinions to all you good people. You
