Calculatrivia
Calculatrivia is a number-based trivia game that was originally made popular in GAMES Magazine. A set of questions, from the obvous to the obtuse, are posed. The answer to each question is a number, though not necessarily an integer. Each of these questions corresponds to a letter of the alphabet (in some cases, the Greek alphabet), which get plugged into a algebraic formula, creating a final answer. In 2002, GAMES regular contributor Bob Lodge created "Ultimate Calculatrivia" which took the game to a new level.
Subsequent to that contest, a portal for GAMES Magazine fans was created online, hosted at [1] There have been at 9 Calculatrivia-style contests hosted there since (as of May, 2005), and there is a community of at least 30 regular contributors.
