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.When the board game was introduced in 1992, Terrace won a number major awards and was subsequently featured on Star Trek: The Next Generation as a permanent prop.1992 Mensa Select - BoardGameGeek
