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.
Demo.

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.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

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.
