One roll. Every day.

Roll a number from 0 to 1,000,000. Find out how rare it is.

RNGdle hands you a single random number every day, then digs through it for palindromes, primes, repeating digits, and other improbable patterns — each one worth entropy points (EP) toward your collection.

What is RNGdle?

A daily ritual built around one random number

RNGdle is a daily random number game. Each day you get one roll to generate a random number from 0 to 1,000,000. Your number is analyzed for interesting mathematical and visual properties — palindromes, primes, repeating digits, sequences, and stranger curiosities — earning you badges and EP (entropy points) along the way. There’s nothing to buy, nothing to lose, and no real-world stakes: just one roll, once a day, and the small thrill of finding out what the universe handed you.

How it works

Four steps, repeated daily

STEP 01

Roll

Press the button to generate your daily number, somewhere between 0 and 1,000,000.

STEP 02

Discover

See what badges your number earns based on its mathematical and visual properties.

STEP 03

Collect

Build your badge collection over time and watch your lifetime entropy points climb.

STEP 04

Share

Show off your roll, its rarity tier, and your badge haul to friends in one tap.

Number rarity

How rare was your roll?

Your roll’s overall rarity is based on total EP compared to every possible outcome. It’s a quick read on how your draw stacks up against the full field of 1,000,001 numbers.

TrashBottom 1%
CommonBottom 50%
UncommonTop 50–25%
RareTop 25–10%
EpicTop 10–5%
AnomalyTop 5–1%
MythicTop 1%

Badge rarity

Every badge has its own odds

Each badge has a rarity based on how likely you are to roll it. Rarer badges are worth more EP toward your overall rank.

Uncommon1–10% of rolls
Rare0.1–1% of rolls
Epic0.01–0.1% of rolls
Anomaly0.001–0.01% of rolls
Mythic<0.001% (1 in 100,000+)

Badges

Your collection

There are many unique badges to collect. Badges recognize patterns like palindromes, prime numbers, repeating digits, meme numbers, mathematical sequences, and more. Locked badges below stay greyed out until you roll a number that earns them.

How does the daily roll work?
You get exactly one official roll per calendar day. Pressing roll generates your number, checks it against every badge rule, totals your EP, and ranks the result against all possible outcomes. Turn on unlimited mode in settings to keep practicing without touching your daily streak.
What determines a roll's rarity?
Overall rarity comes from your total EP compared to all possible rolls, ranked from Trash and Common up through Uncommon, Rare, Epic, Anomaly, and Mythic at the very top.
What determines badge rarity?
Each badge has a rarity tier based on how likely it is to be rolled, from Common at over 10% of rolls down to Mythic at under 0.001%. Rarer badges award more entropy points.
Is my data saved anywhere?
All progress, your badge collection, and the leaderboard live in your browser's localStorage. Nothing is sent to a server, and clearing your browser data resets everything.
Is RNGdle a game of skill or gambling?
RNGdle is a free entertainment game with no real-world wagering, payouts, or prizes. It's built around the curiosity of seeing what a random number generator produces, with no connection to gambling.
