Under Siege is an abstract game played on a circular board by 2 players. One player attempts to move his King piece from the center and completely off the board. The other player attempts to capture the King piece.
Turn based play where pieces move one space per move and capture opposing pieces by moving onto the space occupied by the piece being attacked.
Special moves apply to the larger pieces, namely being able to 'Vault' other pieces of the same team effectively allowing movement of two spaces under specific circumstances.
The King piece cannot capture opposing pieces.
The numbers on each side are uneven, the 'Peasants' have 16 pieces (8 smaller, 8 Larger) while the 'Royalty' have the King and 12 pieces (8 smaller, 4 Larger). This is to balance the fact that the 'Peasant' pieces start the game spread completely around the board, while the 'Royal' pieces are grouped together in the center.
