A few notes/warnings when researching Gambling / Games of Chance on-line:
1.Depending on the game, much of what you get in the first results "Google Search" will be links to "Play Free Online" or other advertising-supported sites. These are not good research sites.
2. Many of those online-gaming sites will be blocked by the school's web-filter. HOWEVER, the web-filter may also incorrectly categorize sites about gambling as "gaming" sites (this has happened with sites about gambling addiction treatment). If you think a site is a legitimate research resource (not a game), we may petition to get it unblocked.
3. If you read the Wikipedia entry for your particular game, you may use the sources they cite, but not the wikipedia entry itself. Always use original sources.

Note: Most online references to this simple dice game say the exact same thing, and cite to a specific book: Musui's Story: The Autobiography of a Tokugawa Samurai.
