Pyramid is a word card game which builds up words from roots and stems. It is "adapted from cards used in a famous vocabulary course". The deck has 72 cards: 32 word roots (green); 16 prefixes (red); 16 suffixes (blue); 6 endings (black); and 2 jokers, one for Greek roots and prefixes, one for Latin roots and prefixes. The word fragments have hyphens to show where they join other fragments, and optional letters in parentheses -- e.g. "-EQU(A)-". Prefixes and roots also have the Latin or Greek source in the upper right corner, with its meaning -- e.g. AEQUUS "EQUAL". The rules for several games are included: - Exec - Flash - Link - Flip - Rote - Solo
