RNGdle Badges
Every RNGdle badge family with its rarity tiers and how EP (entropy points) works — from everyday pairs to the 1-in-100,000 Mythic badges worth screenshotting.
🧮 How badges are scored
Each day RNGdle rolls you one number from 0 to 1,000,000 and checks it against its badge list. A badge is awarded when your number has the property the badge recognises — a palindrome, a prime, a run of repeated digits, a famous year, a mathematical constant. Every badge has a probability-based rarity: the rarer the badge, the more EP (entropy points) it is worth, and your roll's overall rarity is your total EP ranked against every other possible roll.
There is no single "rarest number" — every number has identical odds of being rolled. What varies is how rare a number's properties are, and that is exactly what the badges measure.
🪜 Badge rarity tiers
The official rule (from rngdle.com/about) grades each badge by how often it appears across all rolls:
| Tier | How often it drops |
|---|---|
| Common | >10% of rolls |
| Uncommon | 1–10% of rolls |
| Rare | 0.1–1% of rolls |
| Epic | 0.01–0.1% of rolls |
| Anomaly | 0.001–0.01% of rolls |
| Mythic | <0.001% (1 in 100,000+) |
📊 How the game ranks your roll
Separately from individual badges, your total EP puts your roll into a number-rarity band compared with every other roll. This is the ladder behind the "Bottom 18%" style verdicts:
| Roll rarity | Your EP ranks |
|---|---|
| Trash | Bottom 1% |
| Common | Bottom 50% |
| Uncommon | Top 50–25% |
| Rare | Top 25–10% |
| Epic | Top 10–5% |
| Anomaly | Top 5–1% |
| Mythic | Top 1% |
Note: "Trash" here is the game's own bottom-1% label, not a badge tier. Our calculator uses a similar Common→Mythic ladder at the number level.

🎯 Which badges are worth chasing
For screenshots, the Mythic tier is the whole point. These are the ones players talk about when a roll goes sideways-good:
Everything below Mythic still counts toward your EP and your collection — the pairs, parity and length badges are how most days actually look, and they are what make the rare ones rare.
RNGdle does not publish a complete badge list — only the badges your own account has earned. The names and tiers above are compiled from public community sources and cross-checked against the official rarity rules at rngdle.com/about. Per-badge EP values are not officially documented, so we deliberately do not list them. Expect this to change as the game updates.
❓ FAQ
Is this the official RNGdle badge list?
No. The official game publishes no complete badge list — its site only shows the badges your own account has earned. The names and rarity tiers here are maintained by the community and cross-checked against the rules on rngdle.com/about, so treat them as a good-faith reference that can change as the game updates.
How rare is a Mythic badge?
On the official scale a Mythic badge is one that shows up on less than 0.001% of rolls — roughly one in a hundred thousand or rarer. That is why single-digit rolls, exact jackpots and the constant badges (Pi, Euler, Golden Ratio) sit at the top.
What are EPs in RNGdle?
EP stands for entropy points. Each badge is worth a number of EPs set by how rare it is — the rarer the badge, the more EP it carries — and your roll is ranked against every other roll by its total EP.
Can I check which badges a number earns?
Yes. Our calculator scores any number from 0 to 1,000,000 and lists the badge-style patterns it hits — primes, palindromes, repeated digits, famous years and more — and the sandbox rolls unlimited numbers the same way.
