The solution to today’s puzzle
In my puzzle blog earlier today, I set you the following “common knowledge” puzzle:
Nine balls – marked 1, 2, 3, 4, 5, 6, 7, 8 and 9 – are in a lottery machine. The machine dispenses one ball each to three people, Apple, Bean and Cherry. Each person knows only the number of their own ball; they do not know the balls that the others were given, nor the ones left in the machine.
