Cobweb Court is an original browser implementation of the mathematical pencil-and-paper game Sim, with a Halloween table, computer rival, tactical hints, undo and accessible controls.
Rules research reference: AleksanderGondek/py-friends-and-strangers, MIT, observed 0 stars, last pushed August 12, 2020. This Python repository was not ported or bundled, and does not qualify as a popular recently maintained browser game. We used the original-game fallback after reviewing catalog overlap and candidate suitability.
Original code: MIT. Board illustration: generated with OpenAI's GPT image tool for this game, optimized and bundled locally. The generated lantern table sits directly under the playable web. No runtime image service is used.
