Monopoly - unquestionably has a clouded history and derivation. It's unclear whether Charles Darrow actually invented the game or was merely the first person to market it and make large sums of money out of it. There's no doubt that these property trading board games were prevalent around this era in the States with many different titles and versions of which darrow's is undoubtedly the one that survives with it's legend in tact today.
Darrow was known to be interested in toys and games and is said to have personally carved the houses and hotels for monopoly out of scraps of wood from a lumber yard. He is also said to have used charms from his wife's bracelet to act as the counters used in the game.
What is certain however is the fact that Parker Brothers originally rejected Darrow's game and didn't renew an interest in it until Darrow himself had personally marketed 5,000 sets which he sold at $2.50 each.
After contracts were finally written up between Parker Brothers and Darrow, the company settled a few lawsuits against them which were brought about by people laying claim to have invented the game themselves.
In January 1936 the head of Parker Brothers went on record as saying 'it became the hottest fad the game field has ever known'.
