One soft-body core, two games

Jellygon is available as a free browser demo and a native iPhone game. Its polygons compress, stretch, rebound, and press into one another instead of behaving like rigid circles. Matching shapes merge into the next polygon, and the pile keeps the consequences.

Jellygon and Jelly48 share a two-dimensional soft-body simulation core written in Rust. Jelly48 applies it to a gravity-swiping 2048 board. Jellygon uses it for aiming, dropping, packing, and the occasional merge that rearranges half the cup.

Why the articles exist

The articles are first-hand notes from building and playing the games. Strategy pieces report the test setup, results, and limits. Technical pieces use measurements from the project rather than polishing a tidy story after the fact. Comparison articles disclose the Jellygon affiliation and stay unpublished until the other games have been played.

Drafting and line editing may use AI tools. Ryland reviews factual claims, measurements, and final wording against project source, test output, primary storefront sources, or hands-on notes before publication. The tools can help with expression. They do not get to manufacture experience.

Start with the useful part

If you are here to play, the browser demo starts without an account. If you want the tested advice, begin with five play styles across 250 games. The plain-language physics explainer follows the wobble without requiring an engine diagram.
