A blocked game is when both players are not able to place anymore dominos on the board. this does not come around that often with many of the game types, but I found that in Bergen game type it happens alot!!!
Players must match the end numbers only to get points. +2 For every match and +3 for placing a double down. You also get +2 for winning a round.
Here's what you do.
Difficulty set to beginner
1 Opponent
Domino set of 6
starting hand 7
Try to get you opponent to grab more dominos from the boneyard. Try to make yourself pick up as well to make the game from ending. Try to lock the game when placing all the same number of its kind (7 of each number). Also when all the bones are used the game will end and try to have the low number dominos remaining in your hand. If you win, you will be rewarded the +2 points for winning the round.
Do this 10 more times. Does not have to be in a single game.
