Card game (sort of?), family friendly (non-vulgar), could start a war (delightfully competitive / brings out the best or worst in people). Fits into your bra or shoe. Take it anywhere and everywhere, first dates included.
My favorite speed card game. I have the classic red and yellow tin box. I bring it around with me in my bag sometimes. My friends hate playing with me because I'll win. My other friend loves Bananagrams and always wants to be indulged in a game or two. I think it's cool how so many people have mastered some kind of mostly-useless quirk.
spot it - fantastic card matching game. seems childish, but gets violently competitive. minimum 2 players but you can also play with more. rummikub - if you’re familiar with rummy, it’s quite similar. a fun numbers game that forces you to think outside of the box and eventually impress the hell out of someone. if you don’t like to think, however, and you prefer games that require no skill and are solely based on chance, you will hate this game.
Why not systematically observe, experiment, measure, test, formulate, and modify a hypothesis? Research! Employ the scientific method! Expand your knowledge (and accouterments)! Looking for new kitchen gear? Wirecutter, America’s Test Kitchen, Bon Ap, Cult Flav… you don’t have to listen to them but you can and it isn't lovely to know what makes a great mandolin?
I always pull inspiration from these books. I love reading Andy’s escapades and the graphic presentation of Babitz words in the original Fiorucci book.
