About rngdle
rngdle is a compact browser game about making one random number feel meaningful. Each day you roll a number from 0 to 1,000,000, discover numerical patterns, earn badges, and turn those discoveries into EP (entropy points).
What this project includes
This site focuses on the core play experience: a daily roll, local progress, badge scoring across many pattern families, rarity tiers, shareable roll summaries, and a countdown to the next daily reset.
Progress is stored in your browser. There is no account required to play, and no server leaderboard in this build.
How a roll is scored
After you generate today's number, rngdle runs the reverse-engineered official badge engine (233 badges, 39 supersession families) used by community tools like CubityFirst/rngdle-ep-calculator. Matches award EP; within a family only the highest-EP badge scores. Total EP sets your roll rarity from Trash to Mythic.
Badge rarity
Each badge's rarity comes from its EP via fixed score cutoffs (Common < 1e3 … Mythic ≥ 1e7). Roll card rarity uses EP percentiles across 0–1,000,000:
- Trash / CommonBottom ~1% / below median total EP.
- UncommonAbout top 50% – 25% of rolls by total EP.
- RareAbout top 25% – 10% of rolls.
- EpicAbout top 10% – 5% of rolls.
- AnomalyAbout top 5% – 1% of rolls.
- MythicTop ~1% of rolls by total EP.
