| Jun 25, 2010 at 22:09 | comment | added | Zsbán Ambrus | I love this puzzle too. I first read it on madore.org/~david/weblog/2006-11.html#d.2006-11-20.1390 which also lists a few more well-known puzzles. | |

| Jun 24, 2010 at 17:59 | comment | added | Pietro Majer | This is also a very beautiful puzzle. As to the context, I'prefer to tell it in a less violent fashion: let's say that the director of a private prison offers a free Thanksgiving dinner to his clients if they succeed to win the game. On the mathematical side, there is a less known but very nice additional part: prove that the solution is indeed optimal: no other strategy gives better chances of winning. | |
