Hi All, yes I know it's an old topic :-) but , I felt like having a bit of fun ! , I've just written a GUI TOH using C# and have it working fine - including a "Solve" button which shows an animated solution starting the game from scratch, what I would like to provide , is , if the player ( me ) gets stuck part of the way through a game and needs to see the solution, is , to solve it from the current state of play - my maths fail me here :-( - anyone know how to do this ?
