Let's see if you can figure this one out

I think that the tiles are a different size when they are reconstructed after being split diagonally! Good riddle. :)

Almost not enough to see a visible change. The area of one tile spread over others. The final 7x9 dimension is smaller than the initial 7x9 dimension. Neat effect!

This is not difficult to figure out at all ! Here is his secret.
Every time he moves a section, pay attention to how he drops one of the tiles off the table at the rear edge of the table and when he does this, a tile drops off the table down into his lap. Fast hand movement and the black cloth is how he fools the observer.

An old parlour trick. There's a very slight diagonal gap. Not wide enough to notice, but long enough to have the same area as one square.

I just rewatched the beginning. You're right if you look at the middle of the board you can see a row of tiles that are about 1/2 the size of a full square. (Almost disappointing in a way.....:(

You are correct ! After looking at it again, I, too, could see the slight difference in tile size on the diagonal. Good job catching it !!!!! When it came to my guess about how he was doing it, my blind old eyes had been fooled :(

I don't think its dropping tiles etc...the middle tiles are not full sized tiles, and some diagonal cuts are a bit screwy, but..very well done.

Interesting that the video stops both times he starts taking the tiles out. That's the only time I noticed it stop. Coincidence?? Or the trick?

Back in the 70s I worked in North St Louis and we had the GM Truck plant along with the Corvette Plant in our area of responsibility. On pay days there was a group of kids that would show up and stand near the Payroll Check Cashing Trucks. They had a game called "Three Card Monty" which was similar to a shell game. The workers would bet they could pick the card that was the same card shown at the beginning...such as a King of Hearts. The kids would even put a crease in the card and then move three cards around. They NEVER lost the bets. We arrested some of them for gambling and took them back to the our interview rooms. Even in a controlled environment, watching carefully, we could not determine how they did it...and of course they would not divulge how they did it. If you're good at slight of hand tricks there is no limit to the things you can do.

Well, an old friend of mine came up with what I'm sure is the correct solution, but I still don't have it clear enough in my mind to say I fully understand it. There is apparently no slight of hand involved. The answer lies in the fact that the diagonal cut is not truly straight.
