Cylindrical chess differs from traditional chess in that it is played as if the left and right sides of the board were wrapped around to form a cylinder, which means pieces can go through one side and come out on the other.[more]
The only rule changes are that there is no castling and no en passant. The program only allows legal moves. No warnings are given when a king is in check.
