Earlier quoted context omitted.

I interpreted the description as normal chess board = 2 dimensions. time = third dimension. moving on the x axis in the multiverse as 4th dimension and moving on the y axis in the multiverse as 5th dimension. So yes, in this wacky world a standard game of chess in progress is 3D.

Moving along the x axis is the same as time though.

You're right, I was confused. This is like deciphering Dark on netflix.

I'd think the same way you know you won regular chess. You capture the opponent's king. Checkmate is just an acknowledgement that the current player has no way of avoiding their opponent from taking their king on the next move.

So checkmate in any one timeline counts? You couldn’t do all timelines.

I suppose you would have to avoid the king escaping to another timeline?

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.

How do you know if you have won? Or is it about avoiding checkmate in all possible timelines for all possible time travelling moves?

You only know when you've won or lost when the wavefront collapses to a 3d point you can experience in a particular time.

There's a quantum tic-tac-toe variant which makes some practical compromises to make the game playable and scoreable. https://en.wikipedia.org/wiki/Quantum_tic-tac-toe

It looks amazing, and I really want to play it, but however I count I only end up with 4 dimensions. A chess board is 2D, time back-and-forth is 3D, and going up/down across universes is 4D. What's the 5th? Are they counting real-life-time as the 5th? In which case normal chess is 3D, which seems like an abuse of terms.

It's only 4D. I believe they called it 5D chess because they didn't want people to interpret this as 3D chess + time. If I recall correctly, the tutorial mentions at some point that the 5th dimension is "unused".

It would have been nice if 4D only ever meant four spatial dimensions, and then we'd have (3+1)D for three spatial dimensions and a time dimension. (And (2+2)D for two spatial and two time dimensions :-))

3d chess is another popular variant: https://wikipedia.org/wiki/Three-dimensional_chess Lot of games you could spin up in this manner. I wonder if we are going to do that for all the board games with tried and old strategies. HN has any suggestions on what those board games should be?

> 3d chess is another popular variant: https://wikipedia.org/wiki/Three-dimensional_chess I was crazy enough as a high-schooler to actually build (with the help of my father) a 3D chess "board". It was mostly plywood, with eight 8x8 boards stacked vertically. I had previously gotten a "3D" chess board which was just three 8x8 boards. They weren't making Star Trek tri-dimensional chess sets back then. With the 8x8x8 3…

I imagine it'd be quite hard to trap your opponent with an extra dimension to escape in. Perhaps the board should be smaller to compensate. Regular (2d) Connect 4 is played on a 6x7 board. But 3d Connect 4 is played on a 4x4x4 board.

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