The video at the end reminded me of "Imagining the 10th dimension" https://www.youtube.com/watch?v=8Q_GQqUg6Ts So is this basically visualizing the tree of possibilities from any board configuration, overlaid on itself at nodes where different sequences of moves can result in the same board configuration, allowing you to "jump" to a different "timeline" through the 5th dimension?

Oh my gosh, I hate that "10th dimension" video so freaking much. It has done nothing but spread confusion and false understanding across the internet.

If it were just presented as a fun exploration of what 10 dimensions could be, for fictional purposes, it would be... OKish, I guess. But choosing "10" specifically makes people erroneously think that this is what string theory is about, which is completely wrong.

Additionally, it falls into the trap of assuming that curvature requires a higher dimension to curve in, and that nontrivial connectivity inherently requires such curvature, both of which are false and hard enough to explain to people who have not been explicitly taught wrongly already.

And on top of all of that, it perpetuates the faulty idea that "the" 5th dimension, or "the" 10th dimension are sensible concepts, by presenting its particular choice of dimensions to discuss and its particular choice of ordering of those dimensions as fact.

I always thought a cool chess variant would be quantum chess where you can move a piece to more than one square and assign a probability to each position. Your opponent could do the same. But I never worked out how it could work from there.

There's a quantum chess game on Steam, titled Quantum Chess.

HA ! Of course there is, that always happens to me, I think I am the first to think of something but then of course, a bunch of other people beat me to it :)

A players mental representation of the game is already that (and you use this mental representation to predict future outcomes). If you add probabilistic moves, the optimal way to play would be to give each alternative move the same weight (ie probability) that you think it will win you the game. You would pull this probability out of your mental representation. Something like, "I think this is the best move, but thi…

Yes exactly what I was thinking, it is as if you mentally picture and weight each move, but what if you could actually represent that somehow and play out all the variations of a game like a multiverse. Sometimes when I play against a computer I will try different things by trying something then going back using undo, but then I wonder, wait maybe the other fork would have worked out, etc. This way you could have many versions going at once. I have look at source of various open chess engines and they do something similar, the idea is what if there were a way, maybe with shading of the pieces or some other way of representing the super positions of each possibility. The UI would be interesting challenge.

Have you heard about refusal chess? Each player proposes two moves and the opponent gets to pick the move that suits them best.

When I was learning about puzzle game making, one of the rules was people don't like puzzles. They like puzzles but not the feeling like they're doing one. This is kind of the opposite. So it really competes with Fall Guys then...

Outer Wilds does the whole "puzzle game without feeling like one" better than any other game I know.

God that game is SO GOOD. It gave me a lot of “I finished a puzzle” feeling without having to do any hard puzzles for a lot of it, until the point where I had to take a thing from the Hourglass Twins to another part of the system without fucking it up, with suddenly higher stakes. I stopped playing it for like a week when I knew that was what I had to do, because I had to be in the right mood...

Interesting. When I read "5d chess" I thought it would be a game where each dimension is represented by a different chessboard giving you a different view of the game. So for example, in the first dimension, the white king is in 1a and a black rook is in 2b, whereas in the second dimension the white king is still in 1a but the rook is in 1b, thus threatening the king. So everytime you make a move in one board, the piece you moved moves on all boards, but in a different, but relative, position. So the point of the game would be to make a move in one board that crated an advantage on another board- if a piece is captured in any board, it's captured on all boards and if a mate is threatened in any board it's threatened on all boards (and yeah, that's totally cribbed off the kernel trick in SVMs: map a lower-dimensional space onto a higher dimensional space to find a separating hyperplane that doesn't exist in the lower dimensional space). I guess that would get very hard to play very quickly though, certainly for a full game on an 8 × 8 board, but it could perhaps be played in end games like KRK or simplified chesses like hexapawn etc.

Btw, for anyone who likes time travel paradoxes, do watch Dark. It's up there with Primer, but does your head in more because of how many characters there are.

Maybe you could have the "wave function collapse" when a piece could take another or be on the same square. Would each piece only be able to be moved once before the collapse? Also, I wouldn't have people assign probabilities, but have them pick two moves with a fifty fifty chance of that move occurring. That way they can't just always assign the optimum move the 100% probability.

'From my experience playing a few games on it against decently strong opponents has been that at high levels it becomes "Chess, but it's much much easier to checkmate, and 2~3 times a game some time travel shenanigans happen." The main reason for that is time traveling and dimension hoping come at a tempo disadvantage. When you create a new timeline, you make 1 move, but give your opponent 2 moves. You used your turn…

Without having played it, that seems like a reasonable balance.

Hmm... chess with the feel of poker; that could be fun.
