WEDNESDAY 14 JULY 1965 195th day - 170 days to come
Spoke to Claude on phone. Mentioned the following books:
- MAKE IT YOURSELF GAMES by Robert Reeves (He didn't see it.)
- MATH GAMES & by A.P. Domoryad - Pergamon Books
- GAME THEORY & RELATED APPROACHES - by Martin Shubick.
He saw this in the Math Section of B&N. It contains a game by the author that looks interesting.
Claude told me of another original game by him; called WHAT FOUR? Using pencil and paper a board similar to the following:-
[diagram of four numbered cards on each side N, S, E, W]
One player chooses any number as a start and draws a line to another num- ber. The two must add to 4 or a multiple of four. Then the next draws a new line from this box, to another number so that, again, the two ends add to a multiple of 4, etc. A line can never be crossed. Player drawing last line wins. Changes in the layout can be made. The multiple number can be 3, 5, or even 6.
A similar type word game (see 8/22/64) is now called POLLY-SYLLABLE.
Claude is preparing a book of games and puzzles aimed specifically at school math clubs.
Claude had sent L.O.A. to Martin Gardner. Got a card in reply saying Martin had a large file of board games and has no plans for doing a column on games at the present time.
BB & I played DISPERSAL again. When a player was
within one move of "dispersal" they had to say "threat",
and show the method or methods. If they "dispersed" or
were "dispersed" by opponent without being in a "threat"
position, it was not a win. If "dispersed" without a
"threat" they could move , if possib to protect the "dispersal,"
if such a move available - if not must make a move
anyway, and then announce "threat". Win if opponent
cannot break the dispersal.
Game again took a long time.
