Lost Valley by Tobias and Roland Goslar (Kronberger Spiele/Heidelberger Spieleverlag, 2004) is a wonderful, fascinating game only limited by the fact that it does not support two players. This article intends to change that.

1. Remove from the game all but one of each of the special equipments. That is, available are only one cart, one horse, one canoe, one axe, one fishing rod, one rifle, one sieve and one dynamite. (The question mark chip pool is not altered.)
2. To simulate the activities of imaginary explorers, at the end of every player's turn, not just when the iceberg is in play, he rolls the die. If the result is a 1 or 2, the opponent removes from play one on-board animal, question mark or takeable gold of his choice. A piece of gold is takeable if it is on a river tile, on another tile connected to the river by a canal or on the mountain or triangle tile having an open mine shaft.
3. If there is nothing on board to remove, then instead a result of 1 opens a mine shaft at the mountain location having gold desired by the rolling player.
