Eleusis is a card game that simulates the scientific method and teaches inductive logic. One player (“God” or “Nature”) secretly formulates a rule (a “law of nature”) that specifies what card can be played next. The rest of the players (“Scientists”) take turns playing a card (“performing an experiment”), and trying to deduce the rule (“create a hypothesis”) before the other scientists.
The game can be played with a standard deck of cards, or a special deck can be created.
Eleusis was invented in 1956 by Robert Abbott and appeared in Martin Gardner’s Mathematical Recreations column in the June 1959 issue of Scientific American.
In 2006, John Golden created a streamlined version.
