You have a square 5 x 5 board with four rooks in the corners:
|
Note: for reference, assume the rooks are labeled A, B, C, D as follows:
A B
C D
|
You can move the rooks horizontally or vertically. The only problem is that when you move a rook, it will keep going in the same direction until it hits another rook or the edge of the board.
You want to move a rook into the darkened square on the board.
How can this be done in no more than 10 moves?
1: Move B from E1 to E4 (stops to D)
2: Move A from A1 to E1 (stops to the edge)
3: Move A from E1 to E3 (stops to B in E4)
4: Move A to the darkened square
note: This can be done to all of the rooks.
Note: I didīt peak the other answers (yet :P)
