What I'm going to describe is an actual game played in pubs in Holland,
my question is how to come up with the best possible way to play this game:

You have a paper with the following numbers:

1 2 3 4 5 6 7 8 9

And you throw two dice

For instance a 5 and a 6

Now you can cross off a 6 and a 5 on the paper, or 4 7, or 3 8, or 2 9

Letís say you cross off 5 and 6

1 2 3 4 7 8 9 remaining
Then you throw again, 6 1
Cross off 7
1 2 3 4 8
4,4
Cross of 8
1 2 3 4
4,5 bust (no two numbers combined can make 9)
1+2+3+4 = 10

Add 10 to running total

The object of the game is crossing off as much numbers as possible
and adding up the remaining numbers and add these to your running total.
The first to have a running total over 100 points looses.
