A wonderful blog from a math teacher in Finland who loves Japanese puzzles and mathematics. "Also introducing Finnish habits and the life of a dog owner."

And while we are on the subject, here is a problem about 3 other gods - A, B, and C, called, in some order, True, False, and Random:

"True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer all questions in their own language, in which the words for yes and no are 'da' and 'ja', in some order. You do not know which word means which."

Great play with logic.

Keep your brain sharp while having fun.

Makes sense: Very hard Sudoku books and magazines now become more successful than others. When the going gets tough...
