3 November 2013: Although the Quincala project is still alive, we have decided to close the limited company AB Games Ltd that was set up to deal with the commercial side of the project. Quincala game sets will be sold directly from Ulf in the future. All copyright in the name of AB Games Ltd will be the sole property of the author.
6 February 2013: Sadly, the first official Quincala tournament at the London Mind Sports Olympiad in August 2013 is cancelled. I felt that more analysis was needed before I know if there is a forced draw or not.
1 February 2013: following some deeper analysis of Quincala endgame tactics, I have constructed some positions that look very hard-to-beat, and could possibly turn out to be forced draws. Please see the document The Fortress Challenge - a Forced Draw? for details. The documents Mini Quincala Knocking Game End Game tactics for positions with many towers and Study on the first 8 tower end position are also updated with the new insights from the analysis.

29 August 2012: Many towers end game tactics document updated; the second exhaust example is corrected, and "twin defence" is renamed to "twin response" to avoid confusion with a position already containing a twin of large pieces:
