The K2z server has the puzzles available in their new Windows client. They changed the board slightly, so that instead of a 12x12 corner of a larger board, the board is 12x12. The bottom and rightmost rows were changed to border rows. I am not certain if this would change the answer to the puzzles or not. Most of them would be unaffected. You would have to log on to K2z with this client, in order to see the puzzles. You can then add and retract moves however you like.
I can create 40 separate Jtwixt files, and email them to you, if you like. Instead of using a 12x12 grid, I will use 13x13 grids. This means that row L and column 12 will still be part of the common playing area. This should have no effect on the answers to the puzzles. Note that the puzzles use the old style notation, with letters listed top to bottom and numbers listed left to right. In Jtwixt, in the Board menu, click on “Flip grid labels.”
