Apadobe mine is a small Inglenook shunting puzzle built inside a toy box.

In my imagination the mine is in Arizona or New Mexico in the USA. I’ve included things I associate with these areas: an Adobe building, a wooden water tower and reddish rocks. Yes, this is modelling a stereotype rather than a prototype !

There are eight different wagons, each represented by a diferent card. For the puzzle, five cards are selected at random and the operator must shunt (switch) the wagons to create a train with the five wagons in the correct order.

As you can see, this must be one of the richest mines in the world. It produces diamonds, rubies, gold and silver !
