任务是交换黑白骑士的位置

ENJOY THE BEAUTY AND SYMMETRY OF COMPLICATED MOVES !!!

*** CHESS KNIGHTS INTERCHANGE OR CHESS KNIGHTS SWAP ***

There is a 3x4 chess board with 3 white knights and 3 black knights in this game.

*** Another 4x4 board with 7 white and 7 black knights are added.

*** Board (3x3 or 4x4) can be selected from game options menu.

White knights are placed on the top row and black knights are placed on the bottom row.

*** Select a Knight first by touching it and then click on a green cell to move it in that cell. If there is no green dot after selecting a Knight, that means the selected Knight has no valid move. In this case select another Knight which has valid move. A Knight can't move in to a already occupied cell (i.e a Knight can't attack another Knight).

*** Your task is to interchange (swap) the black and white knights position that is place the black knights on the top row and white knights on the bottom row and try to do it in minimum number of moves.

*** Try to achieve the target state (Knights swapping) in as many ways as you can !!!

Only one knight can be in a square at a time and knight move follows the chess rule

(two and half squares move).

*** Selected knight is highlighted by red boundary.

Undo button reverts back the last move.

Clear button clears the game board.

Green dots represent either the currently selected (highlighted by red boundary) knight's or the last moved knight's possible moves.
