In answer to what numbers we should be aiming for, Tom and Chester from Hotwells Primary School said:

It is better to get the numbers in the middle of the board because then you have more choice and it's easer to get three in a row.

I wrote a table of all the pairs the dice can throw, and then the numbers you can add and subtract to get

 

I then made a table of all the totals you can make, and how many ways of making them there are:

Result	How	No. ways
-5	(1-6) twice	2
-4	(1-5) twice, (2-6)twice	4
-3	(1-4) twice, (2-5) twice (3-6) twice	6
-2	(1-3) twice, (2-4) twice, (3-5) twice, (4-6) twice	8
-1	(1-2) twice, (2-3) twice, (3-4) twice, (4-5) twice, (5-6) twice	10
0	(1-1), (2-2), (3-3), (4-4), (5-5), (6-6)	6
1	(6-5) twice, (5-4) twice, (4-3) twice, (3-2) twice, (2-1) twice	10
2	(6-4) twice, (5-3) twice, (4-2) twice, (3-1) twice, (1+1)	9
3	(6-3) twice, (5-2) twice, (4-1) twice, (1+2) twice	8
4	(6-2) twice, (5-1) twice, (1+3) twice, (2+2)	7
5	(6-1) twice, (1+4) twice, (2+3) twice	6
6	(1+5) twice, (2+4) twice, (3+3)	5
7	(1+6) twice, (2+5) twice, (3+4) twice	6
8	(2+6) twice, (3+5) twice, (4+4)	5
9	(3+6) twice, (4+5) twice	4
10	(4+6) twice, (5+5)	3
11	(5+6) twice	2
12	(6+6)	1

So it is easiest to make $-1$ and $1$.

It is hardest to make $12$ as there is only one way to make it.

Well done Jeremy, we like your logical and well planned answer.

Tables are a great way to write down all your information in a game, so you can discover new things.

Try playing it against the computer and have a think yourself. We'd love to hear from you.
