Kicking off this list smack dab at the bottom is a little game called Kadima, or paddle ball. “Kadima” sounds like the name of a very difficult yoga pose or a highly skilled assassin. Call it what you must, this time-tested beach game will keep you occupied for a total of six minutes. Or until one of you chucks your paddle into the ocean out of sheer frustration. If you’re good at tennis or Ping-Pong, you’ll probably be good at this. If you’re bad at both, maybe just keep going down this list until you find your sweet spot.
