I wrote earlier that sitting straight was important, then a few days later I read that it could be bad for you.
Here is a photo of 2 keen Carrom players using a home made board with bottle tops for Carrom pieces in Java, Indonesia.
They don’t seem to have any posture problems. If I could sit like that I’d be happy. But I’m too stiff now and my joints creak.
Have a look at this site. Go to games index, then Carrom.
A very interesting site, not just for Carrom but all sorts of games.
They have the history of Carrom, Billiards, Snooker, Bar Billiards, Bagatelle, Pool, Shove Ha’penny, Crokinole, Skittles, Indoor Quoits and Bagatelle. These are games that have been around for years, no centuries, and people still enjoy them.
Another plus point. You don’t need batteries for any of these games.
