Does anybody know?

Hi there. Does anybody know the title of this game, or the strategy to win it?

The game consists of 15 lines, drawn in 3 rows - numbering 3, 5, 7. The aim of the game is to be the last person to cross off a single line. You can cross multiple lines out in one go, however they must be adjacent and on the same row.
The layout looks something like this:

        |   |   |

    |   |   |   |   |

|   |   |   |   |   |   |

So yeah, does anybody know the title of this game or the strategy to win it?

Thanks heaps.

Hi Demo;

Your game is close to "normal play 3 heap nim" but has some differences. Try here first.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Does anybody know?

Jane did some in-depth analysis of this a while ago. It was a slightly different game, but it should show you the way to think about it.

Why did the vector cross the road?
It wanted to be normal.
