The rules for Dominoes (DR style)

I've played it alot the times I've been down there and liked it alot. I was trying to teach some friends how to play and the rules have escaped me. Could someone please remind of the Dominican version of the game. Just a quick refresher would probably remind me.

Thanks -- Mike

best played with 4 people 2pairs facing each other play to 200 points first hand starts with the double six if the following person cant go you gain 25 points providing your partner can play if you play a dominoe and nobody else can go another 25 points when the hand is finished you count all the remainding spots on the dominoes if your last dominoe can be played at both ends apart from a double (tapicoua) another 25 or 50 points are awarded. nb its not compulsory but if you play your dominoes like you are going to smash the table every time and have a post morten on your partners playing when you lose your hand it all adds to the atmosphere
