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.
