Math Games – “Sprouts”

with 4 comments

Sprouts is a game based on graph theory that I first discovered through a Martin Gardner article.

Start by placing some dots on a piece of paper. each player then takes turns to draw a line connecting 2 dots and placing a new dot on the middle of the line. each dot can have only 3 lines coming from it. and no lines may cross.

the person who can’t move first is the loser.

here is a simple sample game:

  1. Dear Math Enthusiast,
    Hi. I am a Middle School Math teacher. I spent the summer making a website geared directly for grades 1-8. I want students to have a site where they can practice their math skills while still having fun. I have personally made most of the games.
    If you have a place on your website to put a link, please do so. My site is located at:
    Feel free to email me back with a link or a suggestion.
    Thank you,
    Michael Edlavitch

    there are still 6 possible moves from which the opponent can choose from.

    • No there isn’t. All points have either three curves coming from them or would not allow a curve to be drawn back to itself because it would total four curves.
