ah_clem covered all of his bases on this one saying he'd pass but writing D/T. Clever. While I thought this was a take as experience has shown me that cubes from a prime of X and you have a prime of X-1 in length, they're takes, the cube was far less efficient than I would have thought.

One noteworthy thing is that yes, an immediate six is huge for the doubler but [65 64 62 61] still leave a roughly 70/30 game (obv w/more gammon wins for the doubler). So even though it feels like it's over if the doubler rolls an immediate six it clearly isn't.
