Add the classic board game Snakes and Ladders to the formerly pagan but now acceptable list.
I am too lazy and beerily hazy to provide links, but look it up. It is thoroughly rooted in ancient Indian and Hindu philosophy. Karma, and all that.
I hereby declare that any JW found playing Snakes and Ladders shall be liable to the ultimate sanction. And don't think that Ludo gets you off the hook either.
