For an analogy: an Abelian group is a structure in which four axioms hold. A non-Abelian group is a structure in which three of these axioms hold, and the fourth does not. It is not a structure in which some random proper subset of axioms h

The hyperbolic paraboloid is not an isometric embedding of the hyperbolic plane H2 in Euclidean space E3, because it does not have constant negative Gaussian curvature. In general it is impossible to have an isometric embedding of H2 in E3,

No, you are confusing geometry and topology here. Topology does not change when you stretch the space but changes when you cut/glue it. Geometry does not change when you cut/glue but changes when you stretch. So portals change the

Yeah, Jeff calls it "non-Cartesian". He changes the topology but the geometry is Euclidean. There are also lots of roguelikes doing other experiments with topology, tilings, dimensions (Verdagon 7DRLs, geometry episode of Roguelik

AppStore only accepts games compiled in a new version of XCode, and I have only a very old Mac on which it does not seem possible to install such a new version.

Google Play is not very friendly to small developers who do not want to share their home address (not their fault, it is some recently introduced EU law), but the Android version can be downloaded from itch.io

For Epic, I am using Heroic Games Launcher, I believe it is much better than the official Epic app.

There is a fascinating genre of games where space does not function as in does in our real world. Such games are celebrated, among others, for their mind-bending puzzles, psychedelic 3D visuals, and surreal exploration.

Sure, CDDA is a roguelike -- the word was supposed to mean primarily a specific way of controlling the character, introduced in Rogue. Everybody in the roguelike community calls it a roguelike.

But how much have you played it? When I started working on HyperRogue, I expected it to be a "gimmick or tech demo" as you say. But after implementing the basic roguelike gameplay, it felt surprisingly good, better than what I had

Might depend on the interpretation of "roguelike" -- Rogue combined single-character adventure with grid tactics, so to many people, "roguelike" means single-character grid tactics, usually with some other less unique fe

It is possible to run the game in a Euclidean hex grid and compare. For example: * In Euclidean open space, if you are attacked by two adjacent monsters at once, you cannot escape, because the monsters would just move in parallel lines. In

If you have some static scene in Euclidean geometry, you can possibly also have a static scene in hyperbolic geometry which looks the same*. But the parallax effects when you move would be different, and also that hyperbolic scene likely wo

What do you mean by "weird combos of those"? AFAIK Hyperbolica only has H3 and S3 (and a bit of E3), no combos. (While HyperRogue has all eight Thurston geometries and some more.)

Well, there is "casual mode" which makes Orb of Safety saves permanent, and also the "Orb strategy mode", where a single instance of carelessness of bad luck should no longer end the run (but it makes the game harder in

Hyperbolic plane has tree-like structure. If you tried to draw a binary tree of depth 10 on Euclidean paper, you would run out of space. In hyperbolic plane, the straight lines are diverging and new space is created exponentially (very roug

What would you consider a severe flaw? I see severe flaws even in very popular games :)

Regarding making geometry a hidden component: it, kind of, is a hidden component in HyperRogue. I mean, yeah, it is in the name. But people play HyperRogue without understanding what hyperbolic geometry is. They think it is a game taking pl

More precisely -- you can have x,y coordinates, or (easier to work with) x,y,z coordinates, but you would quickly run into numerical precision issues, and that binary representation prevents that. (Probably it was HyperRogue, other hyperbol

Thanks for sharing! I thought that Circull was a game that once existed for iOS and then was lost, did not know about the web version. (Esfera Chess was another iOS game that was non-Euclidean in some sense and is lost.)

Yeah, it is updated from time to time. Mostly small changes, but the version from 2014 was much less detailed, so better to list it as newer. Currently working on a more detailed "book" on this :)

Addressing hierarchically constructed tiling is quite similar to addressing hyperbolic tilings. Both the "hat" tiling and "spectre" tiling already work in HyperRogue. (Spectre is not yet released but pushed to GitHub.) T

Antichamber has lots of weird, cool stuff in it, but nothing to do with non-Euclidean geometry. (They just use the term incorrectly.)
