The game concept is very good. In fact, I give the game concept 5 out of 5 stars. Unfortunately, the execution of the game board is a bit lacking.
First, the board is small. The squares are much smaller than a traditional chess game board. This, combined with the fact that the pieces are a bit wobbly, makes the game somewhat frustrating because the pieces often fall over.
Second, the game is designed for two or four players, but the board is really only designed for two players. The board should be symmetrical for all four players, but there is only a "bank" to hold the fences for two of the players. Even more frustrating, the board is sized symmetrically for all four players, but for two of the players, the space is just left empty.
If they ever come out with a larger, truly four player edition, I will get it and rate it a five.
