This game, with an ancestry so old it is another contender for the prize of ‘Oldest game in the world’, is known by a number of different names in England – Nine Mens Morris or Morelles or or Merrills or Merels or Mill or just plain Morris.
Whatever it’s called, I used to play it a lot when I was young.
Make sure you follow the rules.
