From the README

A clean-room card duel between Hexons, the creatures of Sixfold, with the old handheld rules, written in Rust, compiled to WebAssembly and played in the browser (Leptos, client-side only). Walk a small world, collect cards from booster packs, build your own decks, beat six rivals and the Hex Warden, then take on the Gauntlet. It installs as an app and plays offline.

Play it: (free, no account, nothing to download first).

Rules engine (engine/): the whole duel, from setup and mulligans through attacks, conditions, Powers, trainers, knock-outs, prizes and sudden death.
