I've never played carrom or skully, but carrom reminded me of a very simple game that we used to play at school - "push-penny". Two or more players had a coin each (same denomination for fairness) and the object was to push other players' coins off the edge of the table by flicking your own at it. A sliding form of marbles, if you like. Was/is this a common game, and does anyone know if it originated from carrom?
