Stumbled across this fiendish puzzle — I don’t have the patience to work it out, anyone else do better than that? (Without writing a program to solve it, wimble… oh OK then, you can if you like…)
Rules of the game:
You have to get all of the characters on the other side of the river: a woman with 2 daughters, a man with 2 sons, a prisoner and a police officer.
To reach your goal, you have to use the raft. The raft can carry one or two persons and can only be steered by the man, the woman or the police officer.
There are some restrictions:
- The little girls can not be left alone with the man
- The little boys can’t be left alone with the woman
- The prisoner can not be left alone with anyone that’s not the police officer
You may be wondering why the little girls cannot be left alone with the man, etc. It is not for the reason you might think.
Edit: For the benefit of those who can’t see the Flash, “X left alone with Y” seems to mean “X is on the same side of the river as Y, without X’s ‘supervisor’ also being present”.
