Anyone know what this game is called?

Answer 1

we played a game like that in algebra it was called Nim. we played with lines on a paper but you can also play using matches

What is the Nim Game? ....... The Nim Game is a game for two players.
It consists of a row of 13 matches. Two players take alternately 1, 2 or 3 matches. The one, who takes the last match, wins.

You also can use coins, cards, beer mats or other things instead of matches.

There are several other nim games with different rows beside this game. I describe them below.
