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. Each number is judged on its mathematical properties and its cultural meaning. Palindromes, primes, runs of consecutive digits, repeated digits, and cult numbers like 42 or 777,777 all carry extra weight. Based on those properties the game assigns a rarity tier — from Common at the bottom to Mythic at the very top — hands out badges for each special feature it finds, and adds to your entropy points, a running total that keeps growing even when your roll is boring.

Check your roll

Paste today's number into the calculator and it instantly tells you four things: the rarity tier, the rarity percentile (how many of the million possible rolls are less rare than yours), every badge the number unlocks, and a plain-English explanation of why the number is — or isn't — special. Everything runs in your browser; nothing is sent to a server.

Rarity tiers explained

Every roll lands in one of six tiers. The table below shows what triggers each tier and how many of the 1,000,001 possible numbers belong to it. The chances are not estimates — they were computed by checking every single number in the range against the tier model described on the rarity calculator page.

Tier boundaries are dleverse's classification model. If official RNGdle thresholds are ever published, this table will be updated to match them.

RNGdle badges

Badges are the collectible side of RNGdle. Each one fires when your number has a specific feature — containing a lucky 7, being prime, reading the same backwards, or landing exactly on 42. A single roll can unlock several badges at once, and they stack with your rarity tier rather than replacing it. Here are six examples from the full list, with the real chance of each one showing up on a random daily roll:

• Lucky SevenCommonYour number contains the digit 7.47% per roll
• Prime TimeRareYour number is prime.7.8% per roll
• Mirror MirrorRareYour number reads the same forwards and backwards.0.20% per roll
• Broken RecordEpicEvery digit is identical, like 55,555.1 in 22,222 per roll
• The AnswerMythicYou rolled exactly 42 — the answer to life, the universe and everything.1 in 1,000,001 per roll
• Edge WalkerMythicYou rolled the absolute minimum (0) or maximum (1,000,000).1 in 500,001 per roll

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.

Rarest numbers ever rolled

Most rolls are ordinary — that is exactly what makes the rare ones worth talking about. Based on our rarity model, these three are among the rarest results a daily roll can produce:

• 42MythicThe Answer to life, the universe and everything — a landmark number that is Mythic on sight.
• 12,321LegendaryA palindrome and a perfect power at once (111 × 111 = 12,321). Double properties are Legendary material.
• 777,777MythicSix lucky sevens in a row — a landmark jackpot and a repeated-digit roll at the same time.
