About · The unofficial tools for a very official game

About RNGdle Tools

Three free tools for people who rolled their daily number and then spent the rest of the evening arguing about it.

🎯 What this is

RNGdle Tools is an independent fan project. It is not the game, it is not run by the people who made the game, and it has no access to anyone's account, streak or leaderboard position. What it does is give you somewhere to keep poking at the idea once you've used up your one daily roll: roll without a limit, score any number you like, and look up what each badge actually means.

🌙 Why it exists

The official game is deliberately small — one number a day, the same number for everyone, a rarity verdict you can't haggle with. That's the whole charm. But the interesting part was never the roll itself; it's the twenty minutes afterwards. Was that genuinely rare? How rare, compared to everything else? Which badge did I just miss by one digit? None of those questions wait politely until tomorrow, and none of them have an answer on the game page. So we built the answers.

👤 Who runs it

A couple of players who got curious about the number distribution and never quite stopped. It's a hobby project: no company behind it, no sign-up wall, no plan to start charging for it. Everything is free and the tools run entirely in your browser.

📊 How the rarity score works

Every number from 0 to 1,000,000 gets a score built from six kinds of signal — its length, which digits it uses, whether digits repeat, what the digits add up to, whether it has a nameable mathematical property (prime, palindrome, perfect square, a famous year), and whether it lands on a documented badge. Each signal is weighted by how often it actually appears across the full range, so rare patterns lift the score and ordinary ones barely move it. It is our own estimate, made for fun and for arguments — it is not the game's EP, and it isn't official. The calculator page walks through every signal in detail.
