Wreckage features 3 new pieces: the Detonator, Dragon and the Flying Guillotine.

Wreckage is played on a larger 10 x 10 square board, and features the following pieces:

The Dragon
-----------
Moves passively like queen or knight.
Captures by sliding towards enemy piece and stopping short in all forward directions (N, NE, NW). Also Captures by withdrawing from an enemy piece backwards and sideways (directions S, SE, SW, E and W).
It Cannot capture Pawns or Ninja Pawns.

The Detonator
--------------
Moves passively like queen or knight. Detonates all adjacent pieces except Ninja Pawns.
Detonation counts as a turn and it does NOT move when carrying out detonation.
Click on enemy piece surrounding detonator to activate the detonation.
If there are multiple pieces to detonate start by clicking on the enemy pieces in this this order: n, s, e, w , ne, nw. You only have to click one enemy piece, the rest will be removed, but Zillions is picky on which order you click or it wont allow you to remove the pieces.

The Flying Guillotine
----------------------
Flying Guillotine moves like a Queen and captures by flying over enemy, and landing on empty square immediately beyond.
It also makes a special capture by replacement 2 squares away, and can also jump over an adjacent friendly piece.
If there is one enemy piece adjacent to it and another immediately after on same line, the Flying Guillotine takes out both pieces and lands 2 squares away.
One Flying Guillotine can be dropped by a side into an empty space on the backrank. Dropping counts as a turn.

The Ninja Pawns:
----------------
This special pawn can move/capture like a regular pawn as well as move 1 space sideways. When in enemy territory it can also capture 1 space sideways.
It can move 1-multiple spaces toward the center and en-passant does not apply. From the middle it moves 1 space into enemy half of board after which it can move forward either 1 or 2 spaces forward.
Up to 5 Ninja Pawns can be dropped (1 per turn) to an empty space on the 2nd rank , and you can optionally make the forward thrust in the same move.
Clicking on an empty square in 2nd rank will drop a ninja pawn. The program then waits for you to make the forward thrusting move.
If you choose not to make the forward move, CLICK ON the ICON for PASS MOVE or from the menu: Select PLAY and then choose PASS MOVE.

See the piece help/description for more info.

Rule Changes:
--------------

1. Flexible Castling - The king can castle by moving 1 to 4 squares towards rook. The rook always ends up next to the king on the other side as in standard chess.
   The choice of castling depends on whether it is more desirable to immediately have the rook in the center file or the king tucked away at the wing.

   When carrying out 1 step castling, Zillions pops up a box asking to choose a move.
   The second move indicating kings move AND the rook to move to king square is the castling move.

2. The standard pawn move is modified slightly – it can now move multiple spaces towards the center (rank 5 for white rank 6 for black). Then it moves forward just 1 space to reach the enemy half of board, after which it can move forward 1 or 2 empty spaces at a time

   En-passant is modified to accommodate this. A pawn that attempts to bypass an enemy pawn by making a double or triple move is captured En-passant.

   This En-passant only applied to standard pawns. Ninja pawns cannot capture or be captured this way.

3. Pawns and ninja pawns promote in the last rank to any piece.
