- Windy City Weasels Diplomacy League: Our league is the most active in North America. We average more than two games per month. We play games at members' homes, in bars, and other venues. We score all of our games using the Sum of Squares scoring system, and each player's best three scores count toward the season standings. Each season runs from September through August. The top dues-paying Weasel at the end of the Season wins our coveted Weasel of the Year title and also the top seed in the Weasel Royale club championship game. We also award Best Country awards to the top dues-paying member of each country, with the caveat that no player can win more than one Best Country award. In addition, we award Rookie of the Year to a newcomer each year. The winner of this award does not have to be a dues-paying member. We usually play our bar games on weeknights, starting at 6:30 p.m., typically. We use a fast clock and always end no later than 11 p.m. House games are usually on weekends and normally are open-ended.
- Bar Room Brawl Series: In addition to counting as regular league games, we track bar games separately in a subset of our league called the Bar Room Brawl Series. Again, each player's top three bar game scores count in the standings. At the end of the season, the top seven players, regardless of membership status, will be invited to compete in the Bar Room Brawl Championship Game.
- Red Wednesdays: Starting in October 2014, the second Wednesday of every month will be Red Wednesday at the Red Lion in Lincoln Square. Join us for dinner, drinks and Diplomacy on Red Wednesday, the second Wednesday of every month!
- Thunder Thursday: Starting in January 2018, the fourth Thursday of every month will be Thunder Thursday at the Scout in the South Loop. Honor the Norse god of thunder on the fourth Thursday of every month!
