How Rarebit works
Rarebit is a daily RNG game: it gives you one number a day, drawn at random from 0 to 999,999. The server saves your roll before showing it, so reloading brings back the same number. A new daily roll arrives at midnight New York time; practice rolls are unlimited but never ranked.
Every number is checked against 53 badges in six families: digits, primes, shapes, constants, calendar and clock, and culture. Rarer badges are worth more points, and only the best badge in each family counts, so a high score means a number is unusual in several different ways.
Tiers and ranks
All one million numbers have been scored, so every roll has an exact rank. Numbers with the same score share a rank, and your tier comes from it, shown in words as well as colour.
| Tier | Rank needed | Share of numbers |
|---|---|---|
| Legendary | Top 0.1% or better | 0.1% |
| Remarkable | Top 3% or better | 2.93% |
| Rare | Top 10% or better | 7.03% |
| Notable | Top 25% or better | 16.29% |
| Neat | Top 50% or better | 28.73% |
| Plain | Below the top 50% | 44.92% |
Numbers with the same score share a rank, so ties at a tier boundary go to the better tier.
Two kinds of rarity
Every number has the same 1-in-1,000,000 chance of being rolled: 999,999 is exactly as likely as 3,842. What Rarebit measures is how rare a number’s score is. A palindromic prime such as 101 ranks in the top 0.05%, though it was no harder to roll, while 18% of numbers earn no badge at all. Numbers in the lower half show a Bottom % instead of a Top %, so “Bottom 18%” means only 18% of numbers score the same or lower.

How to play Rarebit
- Press Roll today’s number once a day. Your number is drawn at random from 0 to 999,999, and the same roll comes back if you reload.
- Read your badges: every pattern the number has, with its exact odds. The best badge in each of the six families counts toward your score.
- Check your tier and rank, explore any number in the calculator, and take as many practice rolls as you like.
Is Rarebit free, and do I need an account?
Rarebit is free and needs no account. Your daily roll is kept for this device without signing in, and an optional DailyPlay account keeps your rolls across devices.
How often can I roll?
You get one daily roll per account or device, and it resets at midnight New York time. Practice rolls are unlimited, but they are never ranked and never replace your daily number.
Is every number equally likely?
Yes. The server draws each daily roll evenly from 0 to 999,999 with a cryptographic random source, so every number has the same 1-in-1,000,000 chance. What differs is how many patterns a number happens to have.
How is the score calculated?
Rarer badges are worth more points: a badge half as common is worth 10 more. Only the best badge in each of the six families counts, and those are added together. The exact formula is on the how it works page.
What does Top 2% mean?
It is your rank among all one million numbers, shown as a percentage: rank 20,000 is the top 2%. Numbers with the same score share the same rank. Numbers in the lower half show Bottom % instead: Bottom 18% means 18% of numbers score the same or lower.
What is the best possible number?
999,999 scores 587 points, the highest of all, and 2,048 is second with 560. At the other end, 179,035 numbers earn no badge and score 0.
Can I check how rare any number is?
Yes. Type any number from 0 to 999,999 into the Rarebit number calculator to see its badges, score, rank and tier.
Is Rarebit connected to RNGdle?
No. Rarebit is an RNGdle-style game with its own badges, names and published odds. DailyPlay is independent and not affiliated with RNGdle.
