Roll. Discover. Keep the good bits.
- Take your daily roll. Press “Roll my number” to get your number. It’s generated on the server, so changing the page won’t change your result.
- See what’s hiding in it. Prime numbers, mirror patterns, repeating digits: all sorts of small coincidences earn badges.
- Build your collection. Keep the badges, add the luck points, and come back tomorrow for another little surprise.
- Share your moment. Copy your result for friends, or compare real rolls on the daily and all-time leaderboards.
This number reads the same in both directions. It earns Mirror Mirror, plus Oddly Satisfying and Double Take. That’s 380 luck points, all from one roll.
Good things come in all rarities.
A higher number isn’t automatically a better roll. Points reward properties and patterns. A humble-looking number can hold several surprises at once.
Explore all 36 badges to see the exact conditions, approximate one-in-N odds, and points for each discovery.
A collection with somewhere to go.
The 36 discoveries form six themed sets. Complete a set to earn its collector title on your public profile. Tap any badge for a worked example, its probability and the last time you found it. Set progress and titles are cosmetic: they never improve your chance of a rare roll.
A little luck is better shared.
Public rolls can appear in today’s best and recent discoveries. Visit a player’s collection, open a shared roll to explore its patterns, or give it a heart. You can appreciate another player’s roll once per browser profile and remove that appreciation later. Your stats controls whether your profile and rolls are public.
When badge rules expand, existing numbers and dates stay unchanged. Saved results are re-evaluated against the updated collection so scores and leaderboards use the same rules.
Is RNGdle a guessing game?
No guessing required. Press the button and a random number finds you. The fun is discovering the patterns in that number and collecting the badges they earn.
When can I roll again?
Every day at 00:00 UTC. The countdown on the game page shows exactly how long remains. Refreshing the page brings back your existing roll, so you never lose a result.
Does everyone get the same number?
No. Each player receives an independent random number from 0 through 1,000,000, inclusive. Every one of those 1,000,001 numbers has the same chance on each roll.
How are points and rarity calculated?
Each badge has a fixed point value shown in the collection. A roll earns the sum of all its matching badges. Its percentile is the share of all 1,000,001 possible rolls that earn strictly fewer points. Common is below the 50th percentile; uncommon starts at 50, rare at 75, epic at 90, legendary at 99, and mythic at 99.99. Tied scores share a percentile.
Do the zeros at the start count?
Yes. Numbers below 100,000 are displayed with leading zeros to make six digits. Digit-pattern badges use those displayed digits. For example, 001100 is a palindrome. Mathematical badges such as Prime Time use the actual integer value.
Do I need an account?
You can play immediately. An anonymous profile is saved on the server and linked to this browser with an essential cookie. Your name starts as a random alias; you can change it in Your stats. There is no email, password or cross-device sign-in.
What happens if I clear my cookies?
You lose access to that browser profile and its progress. A different browser or device has a separate profile. This is a casual, cookie-based daily limit, not verified one-person access.
Can I win money?
No. RNGdle is free entertainment. Luck points and badges are collectibles with no monetary value, and there are no purchases, wagers or cash prizes.
