Daily number ritual
One number a day.
This roll is yours.
Each local midnight you get one number from 0 to 999,999, rolled in this browser and saved on this device. Collect a badge for every rare pattern it hides, and see how unusual the roll is.
A perfectly ordinary number. No badges today — tomorrow's roll is already waiting.
A slot machine where the house is math.
RNGdle deals one number per local day, and the number is yours. Friends roll their own. Primes, palindromes, Fibonacci hits, meme numbers and other traits pay out badges and entropy points, so two people can share very different luck.

Frequently asked
Does everyone get the same number?
No. Your daily roll is drawn once in this browser and then locked until the next local midnight. A friend rolling the same day gets a different number. The method is described on the how it works page.
Do I need an account?
No. Your streak, roll history and best score live in this browser's local storage and never leave your device.
What are entropy points?
Each badge pays out EP based on how unlikely the trait is — a twin pair pays pocket change, a six-digit palindrome or a Fibonacci hit pays a fortune. The daily total decides your tier.
What is a free roll?
Another roll from the same random source. It scores badges and EP the same way, and it can add to your album, but it does not replace today's number or extend your streak.
