RNGdle — Daily Random Number Game Guide & Tools

What is RNGdle?

RNGdle is a daily random-number game that works a bit like the word-guessing daily puzzles it shares a genre with — except there is nothing to guess. Every day at midnight UTC, the game draws one number between 0 and 1,000,000, and that same number is served to everyone who rolls that day, anywhere in the world. You get exactly one roll per day. Once you have seen your number, that is your roll until the next reset: no rerolling, no retrying, no paying for a second attempt.

The interesting part is what happens after the roll. The game scans your number for 233 recognisable patterns — palindromes, primes, repeated digits, meme numbers like 420, mathematical sequences, and a long tail of curiosities — and every pattern it finds fires a badge and pays entropy points (EP). Rarer badges pay dramatically more: EP is set to 100 divided by the badge's earn probability, so a 1-in-a-million badge pays about 100 million EP. Your card tier — from Trash and Common up through Rare, Epic, Anomaly to Mythic — is decided by the total. The leaderboard keeps daily, weekly, all-time and badge-specific rankings, with registration required to save your scores.

Three things make RNGdle different from Wordle and its many cousins. First, there is nothing to guess: the roll is pure luck, so nobody is better at RNGdle than anybody else. Second, the result is shared — the entire planet rolls the same number each day, which turns a lonely random draw into a worldwide conversation. Third, the grading is layered: one card tier for the whole number, badges for every pattern it hides, and entropy points that accumulate day after day. This guide walks through all three layers with the real rules.

Check your roll

Paste today's number into the calculator and it runs the official rules — all 233 badges, the family supersession, the exact EP payout and the card tier — entirely in your browser. You get the tier, the top-percentile band (how many of the million possible rolls it beats), every badge unlocked, and a plain-English explanation. Nothing is sent to a server; the practice simulator on this page rolls the same way with your device's dice.

Want the full rules in one place? The RNGdle wiki collects all 233 badges, the seven tiers and the EP economy on a single page.

Rarity tiers explained

Every roll lands in one of seven card tiers, decided purely by total EP. The table shows each tier's EP band and how many of the 1,000,001 possible numbers belong to it — computed by running the official 233-badge rules across the entire range, not estimated.

The bands mirror the game's own percentile design: Mythic is the top 1.0% of rolls by EP, Anomaly the next 4.0%, and so on down to Trash at the very bottom. What the bottom tier actually looks like →

RNGdle badges

Badges are the collectible layer of RNGdle. The game recognises 233 distinct patterns, each paying EP inversely proportional to how often it appears, from everyday finds like Lucky Seven to the once-in-a-million culture exacts. A single roll lights up many at once — roll 420420 and Hotbox, Echo, Three Pair, Low Ball, Flush and a dozen more fire together. These are six examples from the official list:

• 7️⃣Lucky SevencommonContains the digit 7.47% per roll213 EP

How the daily reset works

RNGdle resets at 00:00 UTC — midnight Coordinated Universal Time, the world's reference clock. The moment the reset happens, a new number is drawn for the whole planet, yesterday's roll becomes history, and your once-a-day roll is available again. Everyone plays on the same schedule: a player in Tokyo and a player in São Paulo get the same number from the same reset.

Because UTC rarely matches your wall clock, it helps to translate it once. UTC midnight is 8:00 a.m. in Beijing, 9:00 a.m. in Tokyo, 10:00 a.m. in Sydney, and — for players in the United States — 8:00 p.m. in New York or 5:00 p.m. in San Francisco during daylight saving time. The how-to-play guide has the full timezone table plus the rules in two minutes. (UTC itself is the atomic-clock standard the whole internet runs on — timeanddate.com has a clear primer if you want the full story.)

Rarest numbers ever rolled

Most rolls are ordinary — that is exactly what makes the rare ones worth talking about. These are three of the rolls the engine grades highest and the community loves most:

• 420,420The Hotbox: an exact 1-in-a-million number that also stacks Echo, Three Pair, Low Ball, Flush and more — 100,133,055 EP.
• 825,825An Echo (825|825) with Three Pair on top — the community’s favourite screenshot, and a textbook Anomaly.
• 777,777Six lucky sevens: Jackpot Six, Homogeneous, Palindrome and a Deep Void family sweep in one roll.
