Hey all- anyone out there fill me in on the rules of 2 person Jamaican Dominoes?

I got some down- but feel like Im missing some...

begin with 6/6... play on either end going in a line... matching #s... doubles get layed down sideways...

now- is point keeping a must? Whats the object- is it to block the opponent?

An most importantly... when do I get to smack down my domino HARD and make some bumba references?? hahaha

Fill me in if you can! Thanks everyone
