Spellmaker (1978)

A game of mysticism and magic where players are powerful wizards who, from their enchanted towers cast spells and plan strategy that will speed the innocent princess to their domain.

Magic can change Giants into Toads or Frogs into Knights. The object is to transport the Princess to your Castle to win the game by either defeating opposing forces, changing those forces by magic into helpless creatures or avoiding opposition forces and bringing the Princess home.
