Einsteins puzzle.

Thanks to halogirl, I have this grid to solve:


To solve it, you have to draw one continuous line that passes through each wall once and only once, and it must pass through every wall.

Einstein himself reportedly didnt solve it before his death.

Well this is hard. Don't think its possible. For me it isn't though.

This is not a solveable puzzle as there are more than two rooms with an odd number of sides. It is possible to start outside of a room and then end in the same room and cross each wall only once or to start inside the room and end outside of it also crossing each wall only once.

If you start inside of one five walled room, you can finish that room by moving outside of it and still complete a second five walled room by finishing inside of that one. However once you complete a second five walled room by moving inside of it you are trapped and cannot complete any additional five walled rooms. Since there are three five walled rooms in the grid presented, it is impossible to solve the puzzle if the strictures of the puzzle are followed.

Congrats Associus, you figured out the 'solution'.

Thanks,

I also forgot to mention that if you start outside of all of the five walled rooms, you can only finish one of them.
