Stack
TypeScript grid generator · React PWA · Python clue tooling
Generation
Searches for a symmetric block pattern, then fills it by backtracking, so every published edition is verifiably solvable.
Clues
Drafted by an LLM with structured outputs and stored as drafts with their provenance. Automated validation checks them, and only the review step promotes a draft into the approved set.
Vocabulary
About 2,800 words, extended in batches from LLM drafts and an open KBBI dataset.
Publishing
A scheduled GitHub Actions job generates tomorrow’s edition at 00:10 UTC, and date-gating keeps it hidden until its day. Deploys run over SSH after lint, tests and build pass.
Quality
Over a hundred tests across the grid engine and the Python pipeline, with ruff and CI on every push.
Status
Live. A new edition is generated and published automatically every day.

A new edition every day

Every day a new edition is generated and published automatically. The vocabulary keeps growing in batches of about fifty words, each drafted by a model and promoted through a review step.

It publishes itself

A scheduled job generates and commits tomorrow’s edition each night, and date-gating keeps early ones hidden until their day. No manual step is left in the loop.

Harder at the weekend

Sedang from Monday to Friday, Sulit on Saturday, Sangat Sulit on Sunday. The tiers waited until the vocabulary was deep enough to make them feel different.

Check and hint, with limits

Periksa checks a word or the whole grid and marks wrong letters with a slash, not a colour. Bantuan reveals one letter at a time, capped at three per edition.
