Components of a hard six, in craps

As a detective tasked with solving the mystery of the crossword clue ‘Components of a hard six, in craps’, my thought process immediately turned to the game of craps. I knew that a hard six in craps was achieved by rolling two threes, called “boxcars” in craps lingo. However, the clue specifically referenced “components“, implying that there were two separate parts that made up a hard six. I then realized that a hard six could also be made by rolling a five and a one, or a four and a two. In both of these cases, one of the components would be a three, since three plus three equals six, three plus two equals five, and three plus one equals four. This insight led me to the answer ‘TREYS’, which is a term used in craps to refer to a roll of two threes. So, in essence, the two components of a hard six in craps are two treys. Mystery solved!
