When I was at school violent playground games such as British Bulldog, Jimmy Knacker and the still popular Slapsies were the order of the day, and despite the best efforts of the health and safety, cotton wool cladding, Daily Mail reading, nanny stating, fun killing, idiotic moral majority the odd one or two are still being played today. Strange Games reader Cynthia Curtainpole (possibly not her real name) sent in the delightfully brutal playground game of Crabs.
For 2 players, each holds out their hands and grasps the other's as in the photo with their finger nails held against the insides of the other person's fingers. Now both players squeeze as hard as possible (in a 'crab' like fashion) which forces their nails to dig into their opponent's fingers while all the time their opponent's nails are digging into theirs. The game is to see who can stand the pain and last the longest.
This is a game best suited for players with long (even better, sharp) fingernails. This is a game for tough people. This is a game for girls!
