164th day - 202 days to come
Rcd. a call from John Geiger, a New Jersey city planner. He has a
simulation game called METROPLAN and a series of simpler
games based on the same idea. He wrote to Martin Gardner
and Martin suggested he get in touch with me. He'll come to
Trying the idea I had last night of using 12 3x2 pieces. The
ways of putting them on the board were very limited. Solved the
problem by expanding the board to 9x9 and added adding three
3x1 pieces. This opened it up wide. Made up a set and a rough
diagram of a board and BB tried it. She thought it difficult,
but I think it is good now. FITTING & PROPER.
These are the 15 pieces for the 9x9 board.
[Diagram of 12 2x3 pieces - each piece has 6 squares - 3 or 4 of which contain circles. Plus 3 1x3 pieces with 2 to 3 circles each.]
Another possibility would be a "super-game" on a 12x12 board
using 22 3x2 pieces (as shown) and 4 3x1 pieces.
[Diagram of 22 2x3 rectangular pieces. Each is divided into 6 squares. On each piece 3 to 5 squares contain circles. There are 2 pieces crossed out.]
