<u>Conway</u> is working on a game called <u>HACKENBUSH</u>. A figure is  <br>
drawn in pencil, similar to one shown.
 
[Diagram of a humanoid doll figure constructed mostly of connected loops. "A" is pointed towards neck. "B" is pointed towards left side of torso. "C" is pointed toward the right side of torso.]
 
Players in turn erase one line or loop between nodes. When an  <br>
upper area is completely isolated it "falls" and is    <br>
eliminated. Thus erasing "A" caused the 6 parts    <br>
above to "fall". Erasing "B" does not cause a "fall"  <br>
since "C" is still considered to hold the figure.  <br>
Two play as in <u>NIM</u>. (This can be transformed  <br>
into a "free" and then can be completely analyzed    <br>
by binary notation.)  <br>
[Illegible crossed out.] Martin used some of Conway's material  <br>
in writing the booklet on <u>THE TOWER GAME</u> for    <br>
<u>Frank Armbruster</u>. He sent $50 to Conway from the    <br>
fee Frank sent him, but Conway refused to accept it. He was  <br>
happy to have Martin use the material.  <br>
<u>Elwyn Berlekamp</u>, of Bell Telephone Labs but  <br>
moving to Berkely has been working with  <br>
<u>BOXES</u>. He finds the 4 x 4 dot field as    <br>
shown the smallest of interest. He uses  <br>
the equivelent form shown to the right  <br>
