  • Great family friendly game for really all ages.
Style: Single
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'll really like this game :) ... show more

  • Lives up to its name
Style: Single
My friends and I enjoyed playing this trivia game. Most questions were familiar enough to answer easily, with some that stumped us thrown in. The game lived up to its name as we found ourselves saying, "I should have known that!"

  • A perfect game for a fun, laughter‑filled night!
Style: Single
We played I Should’ve Known That! over Christmas and had an absolute blast. It strikes the perfect balance between easy questions that make you feel brilliant and tougher ones that keep everyone on their toes. No matter your skill level, there’s something in it for you. We had so many laughs, a few “I can’t believe I didn’t know that!” moments, and a ton of fun from start to finish. It’s definitely going to be a repeat game for future gatherings ... show more
