Is there a Jewish origin to the game called kugelach which I played as a child in shul? Does it have any connection to the 5 stones Dovid used to kill Goliat?
It's a form of a game called "jacks" or "knucklebones". See this. When I was young, I palyed with the round "spiky" jacks.
One day, I visited my frum friends and they asked me if I wanted to play "kugelach". I said, "sounds delicious, especially if your mother made them!" I was serious; they burst out laughing, and brought out this bag of 5 golden cubes. I said, "What did your mom put in these things? What happened?" Then they started throwing the kugelach in the air, and it was only then that I realized what was so funny.
Now if someone can explain how a bunch of stones were called "kugelach", I can relive my naiveté.
