# RNGdle.me

> RNGdle.me is an independent daily number rarity game by the Number Rarity Institute
> (数字稀有度研究所). Roll a random number from 0 to 1,000,000 and score EP (entropy
> points) from the true, exhaustively precomputed site-wide frequency of 126
> mathematical, structural and meme traits. Free to play in the browser — no download,
> no account; progress is stored locally on the player's device.
> Bilingual: English is the default (no URL prefix), Chinese lives under /zh/.

## Pages

- / — Daily roll: one number per day, heartbeat digit reveal, rarity verdict
- /analyze/ — Number rarity analyzer: score any number 0–1,000,000 (?n=123321 deep link)
- /infinite/ — Unlimited rolls beyond the daily one
- /quiz/ — Number pattern quiz
- /atlas/ — Number atlas: 46 scored entries + reference entries, exact counts, frequencies, top-scoring examples
- /about/ — Scoring formula, tiers, and site identity

## Scoring

- Each matched trait earns EP = -log2(p) x 20, where p is its exact frequency across
  all 1,000,001 numbers (exhaustive precompute, not sampling).
- Multiple hits in the same group decay by rank: x1 / x0.35 / x0.15 / x0.07 / x0.03.
- Total score is the integer sum of credited per-trait EP; overall tiers are
  percentile-based (Common up to Singularity).

## Notes

- Independent project; not affiliated with rngdle.com, rngdle.net or other similarly
  named sites.
- Meme numbers (e.g. 114514, 42) receive no artificial bonus — their EP comes from
  true rarity alone.
- Chinese page equivalents live under /zh/ (e.g. /zh/atlas/).
