Morpion Solitaire - List of the site's news added June 4th 2008

• Impressive results from Michael Quist:
• Enumeration of distinct possible grids for each game (5D, 5T, 4D, 4T) and also for 3D/3T.
• Thanks to his enumeration, 4T and 4D games are now solved! Their maximum scores are 62 and 35 moves, meaning that the Hyyrö-Poranen records will never be beaten!
• Nice 5T symmetrical grid of 136 moves, and nice 5D symmetrical grid of 68 moves.
• 60 and 34 moves are optimum for 4T and 4D symmetrical grids
• Confirmation of my worst scores
• New record at the 5T game using a different initial pattern, constructed by Marc Lapierre: 187 moves.
• Astonishing remark by Marc Lapierre, never done before: the first record of 150 moves by C. W. Millington in 1972 had really... 149 moves only!!!
• New page on variants, games for one or two players:
• Connector, thanks to Walter Joris
• Morpiae, thanks to Vincent Everaert
• Finite 3D/3T, who can find a smaller score with this new pattern ?
• Scaffold by C. Croft, thanks to Eric Solomon and David Wells
• Interesting remark from Lee Morgenstern: it seems that 3T and 3D games are always infinite. Who can prove that?
• By Daniel Goffinet, two precisions on his testimony: the name of the game was already "Morpion Solitaire" at Paris in 1962/63, and he invented the notion of "potential".
• Because I like this first sentence of his first paper on this game in 1974, quotation of Pierre Berloquin added at the beginning of the Rules page.
