I was thinking of this game the other day and tried to look for a web site and found this one. It is great to know that this place is here. I was trying to explain it to my 13 year old. I grew up in The lower east side of Manhatten and we used to play skulsies as we called it and man did we have fun trying to make the best and fastest cap on the block, We tried big ones and small ones we filled them with anything we could get our hands on, My favorite was a regular bottle cap with pennies and wax. I had a collection of different caps, Some had two pennies and wax and some had one. Man oh man those were the days.
