This is a 2-3-2-3 Quarter the Deucey, if that's helpful. All Trade.
Centers Cast 3/4. The end looking out Circulates, while the end looking in
steps forward into a star. The center star turns 1/2. This is sort of
like the center 2 trading on Spin Chain Thru, but there are two other
people "riding the star". Then those who meet Cast 3/4 while those
who rode the star move forward to the end of the line.
