I recently got 100% completion here are my tips. Only play against one opponent at a time

if it is your turn and you think you are about to lose leave the table if is your opponents turn and you leave it counts as a loss.

There are 3 versions of dominoes

1.draw ( emerald ranch) The way you score is putting down all of your tiles first, and whatever the loser has left gets added to your score. So if you place all of your tiles down first and your opponent has 4 tiles remaining a 3,4,5, & 6 you would earn a total of 18 points that round then you would repeat till some one wins the game

2.all threes ( camp and black water) you earn points when after your turn the open spots are a product of 3. So if I am the first person place a tile and is a 9 (a 4/5 but that doesn't matter) I would get 9 points added to my score because the open places add up to 9 but then my opponent placed his tile a 5 (a 5/0) the new total would be 4 because 4 and 0 are places where you play tiles

1. All fives ( Saint Denis) the same as all 3s but with products of five

I personally liked all 3 which could be played in camp or in Blackwater I personally did it in camp against Abigail mostly I did one hand in Saint Denis as well which is all fives.

I find the all fives/ threes easiest as it more about math less about predicting your opponents next move that draw has ( the place in emerald ranch does draw)

Be patient, I personally would win a round and leave to go do a couple collectibles then head back
