There are 15 stairs arranged in a line. There are 6 people on various different steps.
The only rule is you can only move a person if you move it to any lower vacant stair.
In a two player game, you alternate moving single people. The last one to move a person wins! What strategy should you use in order to win?
What strategy would be used if the people couldn't pass each other when moving down the stairs?

In both versions presented (passing allowed and passing not allowed), the moved person must move to a vacant step. So, while in one case passing is allowed, in neither case is landing on an occupied step allowed, so neither is the equivalent of nim.
