I have been meaning to add Sungka since I have played it a fair number of times (though I didn't know that's what it was called until recently).
Are Congkak & Sungka actually different games? I've read the descriptions of Sungka
on awale.info and as far as I can tell the rules are the same - the differences seem to be in the cultural history & designs of the boards.Dakon
also seems very similar - the only difference being a non-simultaneous start. Wikipedia has
a single article for all three games (in English at least).
