For adults only! From flirty to dirty, sloshy to sloppy, these games provide totally grown-up fun. Even the die-cut cover hints at private delights, with its peek-through keyhole. So grab a drink, lose your inhibitions, and start playing. Out boozing at the bar? Go for the classic but satisfying “Chug,” a technique-testing contest in which you pour the entire contents of a cup down your throat in a single gulp. Or try to think while you drink, with the math-oriented “Buzz” or “Categories.” The penalty for failure? You get “shots.” For something less alcohol infused and lots sexier, manipulate your body in “Naked Twister,” set up a sexual scavenger hunt (with favors for finding the goods), or get inspired by a naughty chat room.
