Rcd. the ''<u>GENERAL</u>'' (July - Aug. '71). There is an auction of <br> | |||
some old games that are out of print. The only one <br> | |||
I am interested in is <u>ADVERTISING</u> a private label game <br> | |||
for Westinghouse TV. Only 1000 were published. <br> | |||
Finished the letter on <u>FANTOCCINI</u>. BB typed it. | |||
To <u>Martin Gardner</u>. He told me more about the visit <br> | |||
recently by several mathematicians. They are working on a <br> | |||
book on recreational mathematics. But Martin thinks it <br> | |||
will be too complicated for the layman. He couldn't understand <br> | |||
a lot of what they were explaining to him. <br> | |||
<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> | |||
[Diagram of a 4 x 4 dot field next to a 4 x 4 box grid.] | |||
