Quarter Rolling Die

Quarter rolling a die means triping it on any of the 4 sides adjacent to its base or face in contact with the flat surface. Using the assembled die and quarter chessboard:

1. You can place and align the 1 x 1 die on any square of the board with its top face pips as initial count.

2. By quarter rolling to any adjacent square once, you just add the top pips number of die on that square to previous count until all 16 square has pip numbers to be added.

How to get a maximum die roll (sum of all top face number of pips) by quarter rolling a standard die on every square of a 4 x 4 checkerboard?
