Pentagram vs. Pentalpha — What's the Difference?

A pentagram (sometimes known as a pentalpha, pentangle, pentacle or star pentagon) is the shape of a five-pointed star polygon. Pentagrams were used symbolically in ancient Greece and Babylonia, and are used today as a symbol of faith by many Wiccans, akin to the use of the cross by Christians.

Pentalpha is a puzzle where the goal is to place nine stones on the ten intersections of a pentagram. The puzzle is used as a confidence trick in Mexico, where it is known as estrella mágica.
