Richard Feynman and his wife were having a holiday in Guatemala. The wife joined a tour and he was bored in the hotel room. He wondered about the strange figures in the tourist magazine. The Mayan numbering system appeared to be based on the number nine, while the Mayan
calendar was still a mystery. Feynman recognized its multi-cyclical nature based on cycles of 240 and 365 days and that very afternoon solved the riddle. Now that I have told you the key, you can easily verify it on the Mexican calendar stone (at the right). Fortunately, still there are ancient riddles waiting to be solved, and here is one.
Three thousand years ago the people in the Middle East had a board game, the first in the world. Recently a complete set of figures was unearthed (see pic) but the board could not be found. The game set consists of colored stones, something must be related to the color in the game. The two main animal figures are pigs and dogs. Considering the shapes and numbers of the stones, it appears that the game is based on number four.
Anybody spending a lazy afternoon in a hotel room? Could you retro-engineer this game?
