Guides
How-to
- Shuffle, pick and weight choicesShuffle, pick, sample and weight with the right function, and keep draws predictable.
- Keep features on separate streamsGive each feature its own sequence so adding one never changes another.
- Make a daily puzzleMake a daily puzzle from a calendar day in UTC or a chosen time zone, and map seeds back to dates.
- Save and resume a streamCount draws, save a position as JSON, text or CSV, and resume from it.
- Embed a picker and use hooksPut the picker element on a page, decide what a shared link reveals, and use the React hooks.
Explanation
- Engine and compatibilitySee the small state of the generator, why the sequence is part of the contract, and what it is not for.
- Seed normalization and reserved rangesNormalise seeds, tell a sequence seed from a distributable one, and reserve blocks.
