Quoridor is quite a complex game: Determining one's next move is nearly always non-trivial.
For example, while the number of moves to win is important in the last stages, the number of possible paths a player has seems to be a key success factor (the fewer possible paths the better).
Most people, including myself, initially look at Quoridor as a game that's going to be too simple to be fun, but that's just not the case.
Well, having played Quoridor solidly for the past few weeks, we can honestly say it's a classic-in-the-making, and it is so addictive you'll be dreaming about pawns, squares and fences every time you blink.
The basic premise of Quoridor is to get your pawn to the opposite side of an 81 square board before your opponent.
Quoridor is simple to play but difficult to master.
