We had a player with Fountain of Reflection. "At the end of the game, score 2pts for each stone of the Type you have the least of."
At the end of the game he was tallying his score and came at an obstacle. He had a tie for the stone type he had the least of; he had 3 each for both red and yellow stones, 3 being his lowest.
How would you score this?
We decided that he received no pts because of the tie, since he technically did not have the least of anything.
If 2 or more colors tie for the least, you count only 1 of the colors. In your example, he would count either red or yellow and score 6 points.
