How RNGdle works

RNGdle is one button and one number a day. Everything interesting happens in the part it shows you for five seconds and never explains again: what a badge is, what EP is worth, and how rare your roll actually was.

🎲 The loop, in four steps

1. Roll. Once per day the game draws a whole number from 0 to 1,000,000. Everybody gets their own draw; the range and the odds are identical for all of us.
2. Discover. The number is checked against 233 badge rules - is it a palindrome, a prime, six of a kind, the year 1984, does it contain 69.
3. Collect. Badges go into a collection that fills slowly, which is the reason to come back tomorrow.
4. Share. The roll card - number, rarity band, badges, EP - exists to be posted somewhere with a caption about your luck.

Step 2 is where every argument starts, so that is what the rest of this page is about.

🏅 Badges: what they are and what they pay

A badge is a named property of your number. Each one carries an EP value and its own probability, and the game bands them into six rarity tiers by how often they turn up. Both columns below come from the game's own table; the third is what the EP value has to be, given the odds.

Multiply any badge's EP by its own odds and 223 of the 233 badges land on the same figure: about 100 EP per roll, on average. That is not a coincidence, it is how the table is priced - a Mythic badge is not worth more per roll than a Common one, it just shows up far less often. Which is the single most useful thing to know before deciding what to chase.

🧩 The family rule, the part everyone gets wrong

168 of the 233 badges belong to one of 39 families. Inside a family the badges are alternatives, not additions: if your roll earns three badges from one family, only the largest keeps its EP and the other two score nothing. The remaining 65 badges have no family and always count.

Roll 1,000,000, the biggest number in the game:

The payers at the top end are One Million (100,000,100), Eon (10,000,010), Contiguous Sixes (10,000,010), 6th Power (9,090,918); among the 17 that paid nothing are Deep Void (5), Epoch, 3rd Power, Contiguous Fives. Anyone adding up every badge they can see will get a bigger number than the game did, and will be wrong. This is why two sites can quote different scores for the same roll.

📊 What a good score looks like

Your roll gets its own band, from where the total EP lands against every other possible roll. The bands are percentile slices, so each row below is both the share of the range it covers and the EP it starts at.

So: the lowest score the game can hand out is 1,759 EP - there is no such thing as a bad roll, only unremarkable ones - the median is 5,802, and a Mythic band needs 162,292. Half of all rolls will never be worth a screenshot no matter how nice the digits look.

🎯 "But my number looked special"

Usually true, and usually irrelevant. Every specific number has the same chance of coming up; what varies is how uncommon its properties are, and a property can feel rare while being common. Repeating digits look special and are worth 900,000 rolls' worth of attention - Six Digits alone turns up on 90.0% of rolls. At the other end, Exact Jackpot is earned by exactly 1 number in the whole range.

The one that keeps coming up in the community is 142,857: a famous cyclic number, and on a daily roll it lands around the middle of the distribution. Rarity is about combinations, not about how good the digits look to somebody who knows number trivia.

🌙 What the game counts, and what this site does

The official site keeps your streak, your badge collection, your favourites and your leaderboard position. None of that exists here and none of it can be faked here. RNGdle Tools exists for the questions the game answers once a day and then forgets: what this badge actually means, what any number would have scored — the RNGdle calculator runs that for any number you type in — and how a run of rolls looks like when you are allowed more than one.

🧭 Where to go from here

The badge rules, EP values and published odds are the game's own, the rarity ladder is the game's percentile curve, and the counts quoted on this page come from running those rules across every possible roll. Nothing here is estimated or sampled; where a figure looks rounded, it is the game rounding its own published numbers.
