 A shortened version of Magie's game, which eliminated the second round of play that used a Georgist concept of a single land value tax, had become common during the 1910s, and this variation on the game became known as "Auction Monopoly".The auctioning part of the game came through a rule that auctioned any unowned property to all game players when it was first landed on.This rule was later dropped by the Quakers, and in the current game of "Monopoly" an auction takes place only when an unowned property is not purchased outright by the player that first lands on it.
