Please explain how to castle in 960.

Hi. I'm a bit unsure if I'm supposed to click the king & then the rook I want to cast with or some other procedure. Can anyone help, thanx

You simply move the King OVER the Rook that you want to castle with.

Eg. Here, you move K (on b1) to the right over [=pass] Rook (on d1) to castle Kingside;

Or to left over Rook (on a1) to castle Queenside...

So if I want to castle k-side in the position below I click on my king & move it over the rook on h1 as though there's another square to the right of h1?

Move your king ONTO the rook.  In the case of your game, moving Kh1 will make it castle.

(Note that this works for castling in regular games, as well.)

Thanx, I'm gonna try it soon. I hope it doesn't just move my king to g1 & block my rook in. That was my fear.

You can move your King ONTO the Rook; but sometimes if the King and Rook are near each other (in Chess960), it is better that you move your King OVER & PAST that Rook.

eg. in position below, you do not want to make mistake of moving you King only to d1 and not O-O     [if your settings = "one-move click"]

Thanx y'all. Got it, it worked fine.

moving the king 2 squares either side also castles effectively.

I am using Windows 8.1 on a tablet and haven't found a way to castle.  My Rook is on h8 and King on g8.   I tried the suggestions above, e.g., try to move the King to the other side of the Rook.  No good.    Nothing else I've tried worked.  Clicked the King and the Rook.  Clicked the King and dragged the Rook.  Dragged the King on top of the Rook.  Nothing.   Am I missing something or is it not possible to castle in this configuration with Windows 8.1?

@mojolake:  If you are referring to this game below, you canNOT castle (Queenside) until your Bishop is moved away from d1; because after castling, the K is on c1 + R on d1 (as in normal O-O-O).

thanks much.   was thinking i was castling k-side.   wonder why i got the board backwards.   Maybe because the kings are already on N1 (but QN1 not KN1) so my brain 'sees' this as king-side.   Interesting question for the chess psychologists.  thanks again.

i usually lose in chess960 coz i donno how to caslte in it lol, but i was always too lazy to ask, thanks for asking my q :D

so you're saying that castling in chess960 is the same as regular castling, but it looks different?

When you castle in chess960, the king and rook end up on the same squares as they do for standard chess.

This confused me for a long time. I was convinced chess-com had a bug . You'd think castling would put your king 2 spaces left or right (or 1 if there is insufficient space), and the rook to the inside of the king.
The way it was implemented doesn't much sense on a pure 960 basis, but does if you're trying to maintain parallels with conventional chess.

As an aside -- chess24 keeps king and rooks on their conventional squares, and so this isn't an issue.
That leaves 5 squares. 3 choices for the same-colored bishop, 2 for the opposite-colored bishop (6 total so far), then there's 4 choices left for the queen (24 options total). The last two squares go to rooks. So 24 total configurations, or 23 if you eliminate the conventional chess position.
