Here's a cool little logic game... in Japanese. The rules are:
-The Mother can't be on the same side as the Sons without the Father
-The Father can't be on the same side as the Daughters without the Mother
-The Criminal can't be on the same side as the Mother, Father, Sons, or Daughters without the Policeman
-Only the Father, Mother, and Policeman can operate the raft.
