Terrace board game rules

About Terrace, from BoardGameGeek:

Terrace is a strategy game that is played on a three dimensional board with 64 squares of one color, which are arranged in L-shaped levels ("terraces") that rise stepwise from the board's lowest points in two diagonally opposite corners to its highest points in the two other corners. All pieces are shaped alike and move alike, but they are of 4 different sizes, and the smallest piece has the letter T carved into it. The object is to win either by moving your T from its starting point at one corner to an opposite corner, or by capturing your opponent's T.
