About RNGdle
Play RNGdle, a free daily random number game. Generate one integer from 0 to 1,000,000 each UTC day and discover which of 233 mathematical badges it earns. Prime numbers, palindromes, repeated digits, sequences and hidden equations all contribute to its story. Entropy points (EP) reward rare patterns: a badge awards round(100 divided by its exact probability). Within each badge family, only the highest-scoring badge adds EP; other earned family badges remain visible. Number rarity compares the result with all 1,000,001 outcomes. Sign in before generating to save your daily rolls, collect badges and join the leaderboard. Guests can play without an account. No download, paid rerolls or cash prizes.
How to play RNGdle
Press Generate once per UTC day. Watch the digits reveal, then read Badge Breakdown to see your patterns, highlighted digits, rarity and entropy points. The next roll unlocks at 00:00 UTC.

One daily number. A world of patterns.
Press Generate to reveal your number, then read its badge breakdown. Primes, palindromes, matching digits and sequences can all earn badges. Related badges share a family, and only its highest-scoring match adds entropy points.
Your next roll unlocks at 00:00 UTC. Play as a guest, or sign in before generating to save server-recorded rolls, collect badges and join the leaderboard. There are no paid rerolls.
Check a family subtotal before adding badge points
Consider 112234 as a worked example from the current rules. Its opening 1122 earns Contiguous Two Pair, while the same number also earns Two Pair, Contiguous Pair and Pair. All four belong to the PAIRS family, so that family's contribution is 3,957 EP from Contiguous Two Pair. The smaller cards remain earned; they are not extra points to add again.
That is only the PAIRS subtotal, not the whole score for 112234. Other matching families and independent badges contribute too. The RNGdle guide's calculation example shows the matching-outcome count behind those points. This is an example for understanding a result, not a number you can select for your daily roll.
Choose a look and keep the right record
RNGdle on FoolFish Games has two companion editions: Fish RNGdle uses ocean badge artwork, and Animal RNGdle uses woodland artwork. Their daily draw calculations and badge values match this edition. Fish RNGdle also adds a local three-digit catch after the roll; choosing a theme does not improve the daily draw odds.
Each edition keeps its own daily attempt and account record. A roll in one does not fill the other edition's history or combine their lifetime EP. If you switch editions, check the game title and your sign-in before generating; the Animal guide explains its collection view, while the Fish guide follows a real ocean-themed result.
When to choose Fish RNGdle
Compare Fish RNGdle with this edition: RNGdle focuses on the daily number, its patterns and EP. Fish RNGdle retains those systems and adds the three-position catch, giving you a local optimization task after the random result.
Common questions
Can I reroll today’s number?
No. There is one roll per UTC day. Refreshing restores the result; there are no paid rerolls or unlimited practice draws.
Do all earned badges add EP?
No. Only the highest-scoring badge in a matched family adds EP. Lower family badges remain earned. Unrelated scoring badges stack.
Can I sign in after rolling to save the guest result?
No. Sign in before generating to save a roll to your account. A guest result cannot be claimed afterwards.
Can I use Fish or Animal RNGdle to continue this edition's badge collection?
They are separate editions with separate daily attempts and account records. The current badge rules match, but a Fish or Animal roll does not transfer its badges or EP into this edition.
