I asked astra to make playable 4D chess

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.

amelius | 20 hours ago

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

In game design, restraint can be a virtue.

K0balt | 19 hours ago

Yeah, if it was properly 4D it would be pretty unplayable I think, you’d need 4 each 4 layer cubes, and they could not be nested in any physical configuration.

amelius | 19 hours ago

You can show them as 4x4 boards of 4x4 squares.

K0balt | 13 hours ago

Yes, but they can’t be meaningfully nested like the proposed one is. Thats the elegance of The solituon provided, but it necessarily sacrifices symmetry to get there.

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?

[OP] mikiyas | 17 hours ago

yes, a single prompt:

"Create a single html file 4d chess game. By 4d it means 4 dimenstional space. It needs to be playable with understandable rules."

It created the working game with the four boards but since it was impossible to understand from just the board I told it to add a Tesseract.

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?

[OP] mikiyas | 17 hours ago

Well it did make a very good search function that is almost like stockfish for humans in 4d chess

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)

thousand_nights | 20 hours ago

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):

This is clearly not the same thing. Other than both of them adding additional dimensions to chess they have nothing in common.

12a6a | 19 hours ago

Do humans have to search all 10000 4d-chess ideas before LLMs to find the exact one that was plagiarized?

omnicognate | 19 hours ago

[OP] mikiyas | 17 hours ago

that has 32 pieces this one has 20 not to mention that the peice setup and how the pieces travel across dimensions is totally different.

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.
As long as it keeps AI in the news

dwallin | 19 hours ago

I’m just trying to understand, there’s an issue you’ve been unable to deal with for a month, and Astra not being able to handle it in 36 hours is disqualifying?

Keyframe | 19 hours ago

On and off for a month, not straight month and not dedicated time. I am quite confident I will be able to solve it within a week or two of dedicated time. Here, on the other hand, we have this supposedly powerful thing that can do magic, unlike myself. We'll see. I'm not even confident, by looking at what it does, that it will even be able to solve it. Only thing I saw that I like is it's better in communication style compared to Fable and Opus.

Long time ago I had one particular hardware issue, which Opus 4.6 found a workaround to fix. I don't remember the workaround and being careless (I thought I could ask an LLM again if I needed) I lost that solution. Some time passed and I needed it again - neither one of the newer models is able to come up with a nice solution I had back then. They can solve the issue and find a different workaround eventually, but not as nice. On a side note, I could use 4.6 again of course and try to reproduce it, somehow I only thought about it now writing this comment.

Anyway, my point is that I think these frontier companies are advertising their one-shot model abilities, but underneath the models aren't getting so much better as they try to make you believe.

Have you tried turning it on and off? More seriously try to remove agent memory or make it refactor it or go through the docs and look for inconsistencies.

But I still don't know how people work with codex when it keeps resetting the context so often, I mean it's surprisingly good at making notes to itself and can follow a long task, but if there are multiple instructions it sometimes forgets some of them.

Keyframe | 19 hours ago

I just did that and turned on max, let's see if that thing is more of a force!

therealdrag0 | 18 hours ago

Can you say anymore about the issue it can’t solve?

MeteorMarc | 19 hours ago

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

navane | 19 hours ago

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.

omnicognate | 19 hours ago

I think this (from 2000) describes exactly these rules: https://www.zillions-of-games.com/cgi-bin/zilligames/submiss...

There are many, many other such games with all sorts of variations on the rules.

For the record: Once you had found the source of plagiarism, the entire submission was flagged from the front page within 10 minutes.

The reach of any embarrassing news must be limited, and there are hundreds of new AI advertisements in the pipeline that will crowd out this one.

[OP] mikiyas | 17 hours ago

that's a totally different game. It has 32 total pieces while this one has 20 and the piece configuration is also completely different.

I made 3D sudoku, books on paper called SUDOCUBE, with a coded index for the clues, using Opus 4.7 I think it was, which came up with the algorithm and extended my own pre-LLM Kakuro codebase:

Have you seen ColorDoku or MeowDoku? Much better for me to fill colors than numbers. Colors would fit perfectly in a 3D cube, just an idea

mypalmike | 15 hours ago

A couple years ago I wrote a rough CLI based proof-of-concept of a different form of 3D Sudoku. Funny enough, just this morning I was thinking about using Claude to turn it into something actually playable.
