Why are people so thick when it comes to playing "The Knight"? Look guys, the knight's move is defined as 2 moves along either the x-axis or the y-axis. That's the first part of the move. So you must go something like this
^ Either Up/Down 2
<- <- X Or Left/Right 2
THEN you move perpendicular to that axis. Seems simple right? APPARENTLY NOT.
Because the knight is airborne in chess for the first part of its move, people assume that you can move, say left one and up two because it results in the same movement. BUT THEY'RE NOT THE SAME MOVEMENT. The path is different, making them different moves.
When people play Casual, they complain that there must be a bug because they can't go to places they assume they should be able to go. Something like this
K - Knight
o - Intended Move
x - destroyed tile
. x .
. . o
K . x
The move is illegal because you have to run past a destroyed tile before you make the move. No, you cannot move up one and right two because THAT IS NOT HOW THE KNIGHT MOVES. The knight has to make the two tile move FIRST then move perpendicular to that axis.
It's not a bug, and I've explained this several times. I've explained this several times, and I even put in the help files (which people ignore? I guess?) that you must move TWO TILES IN A CARDINAL DIRECTION FIRST AND THEN ONE TILE PERPENDICULAR TO THE DIRECTION YOU TRAVELED!
Look, even without me telling you all of this, if the knight could hop over tiles in casual, wouldn't it be the same as in The Knight's Tour? Why would I even offer the option to switch modes if they were the same game? Seriously!
