Made a set for CONSTANT CHALLENGE. Didn't take too long and was very attractive.

More work on WINDOW PAINS and finally decided to eliminate starting with card #6 as a false trail since I found several false solutions. BB, Dale, and her boyfriend Phil tried it a little bud didn't find it too fascinating.

To the Laurences. Played three games of SEARCH.
The first was played with the rule that a two-factor question called for passing of cards and a one-factor gave just the number. Everyone used their choice cards for a two-factor question and the game was very slow moving. The one-factor cards were hardly even used.
Second game was played with a new rule. Players, if they had the proper cards, could ask a one-factor question and a two-factor question as part of the information.
Third game was played with same rules, but with two unknowns. This in my opinion was by far the best.
Later thought of another idea, but didn't have a chance to try it. The player of whom the question, or questions if two are asked, then is the next to ask a question.

Rcd. a letter from Bruce R. Trone (Phil Cohen's friend). He sent me the rules SIMPLE SPACE CONTINUUM CHESS and challenged me to a game.

Rcd. some further info %amp; a letter from Varigraph about their game DOOP.
