🎯 How you earn it
The rule as the game writes it: Divisible only by 1 and itself. Enter any number from 0 to 1,000,000 into the RNGdle Calculator and it tells you whether that one qualifies, along with every other badge the same roll pulls in.
🔢 The smallest rolls that earn it
| Roll | Badges it hits | Total EP | Roll band |
|---|---|---|---|
| 2 | 16 | 119,610,065 | Mythic |
| 3 | 16 | 112,146,596 | Mythic |
| 5 | 16 | 115,540,709 | Mythic |
Read the total column separately from the badge. A badge is one property; what the roll scores is everything it happens to have at once, which is why the smallest prime number roll and a mid-table roll can look nothing alike.
🧩 Where it sits in the family rule
Prime Number belongs to no family, so it is never outranked: whenever your number earns it, the full 1,274 EP goes on the total. That makes it straightforward to plan around - if the rule fits, you are paid.
🗂️ Where it fits in the 233 badge register
The game bands badges by how often they turn up, and Prime Number lands in Uncommon - the band the game describes as 1-10% of rolls, carrying under 10,000 EP. That is the one rule the whole pricing table follows: a badge is worth more precisely because it almost never happens, so Prime Number at 1,274 EP is rare rather than generous.
The game files it with 🧮 Mathematical Constants. The full RNGdle Badges page shows every badge with its rule, EP and odds, and the pattern guide groups them by the kind of thing each one looks for.
The rule text, EP value, tier and published odds are the game's own. The counted share - how many of the 1,000,001 possible rolls actually earn the badge - comes from running the badge rules across the whole range, which is the same code the RNGdle Calculator uses, so the figures above and the tool agree by construction rather than by copy.
