'The Twelve Pointed Star Game' printed from http://nrich.maths.org/
The game is for two or more players.
Each player chooses one, two or three numbers.
Players then take it in turns to roll two dice and add the scores.
The player who has chosen that number puts a counter on the appropriate circle.
(So for example there's me and my friend Zac. I choose $2$,$4$ and $6$, Zac chooses $7$,$8$ and $9$. Zac rolls the dice and it's a $4$ and a $2$ - so I can put a counter on $6$)
The winner is the first player to have counters on all three circles belonging to one of their chosen numbers.
Play the game a few times.
Here is a copy of the star
