  • Patent number: 4240213
    Abstract: The present educational amusement device includes a horizontally pivoted balance arm and several pairs of matched game pieces. The game pieces of each pair include one which displays a non-verbal symbol and another one which displays the word for that symbol. The game pieces of each pair are equal in weight to each other but different in weight from the game pieces of every other pair. Therefore, the balance arm will assume a horizontal position only if two game pieces placed on it belong to the same pair. A downwardly extending front wall of the balance arm presents a window which registers with and fully uncovers a smiling face symbol on the pivotal support for the balance arm only when the balance arm is horizontal.
