A quick reminder as to just how bad I am at classic chess, but this is really fun and brain bending

I was expecting it more like a filled hypercube but its more like two surfaces? Probably better the way it is.

If it is only 4x4x2x2 then this has fewer hypersquares than a proper version of 4D tic tac toe, e.g.:

Excellent job, this was very fun to play.

I liked the explanations, graphics, interactive tesseract, all nice attentions to detail.

How much guidance did you give Astra? Did you give a single prompt, an example site to mimic or was there more to the design and make process?

Not astra made but my mom and nephew say it's a fun thing to play https://chesspoly.com (https://apps.apple.com/gb/app/chesspolly/id6798789898)

Did it also make a 4D chess Stockfish 19 for you?

I think flipping the tiling between light and dark on the top left and the bottom right (or vice versa) would make more sense. Then bishops stay on one color and the knight always alternates between colors (like 2d chess)

very cool. that being said, I have never not wanted to play anything more than this :D

Very cool! (For learning/ease of use, it would be helpful for me to be able tap enemy pieces to see where they could go next. (But with a different indicator.))

"i made this!" No, Astra didn't "make" anything. It plagiarized from old ideas before LLMs like (2020):

I asked Astra to try and fix an issue in my codebase I've been battling for a month. Day and half later on high and it's still circling the drain. Seems like with each new model we praise it based on toys, but then reality hits the ground soon and we wait for the next model. In the meantime, good ol' brain.

It feels unnatural that a white bishop can move to black squares.

There is already 5d chess, it's been out for years on steam. It's very polished, has tutorials and puzzles. Time travel and parallel universes.
