What are palindrome numbers?

Palindrome numbers are integers that read the same forwards and backwards, such as 7, 22, 121, or 12321.

Is 10 a palindrome number?

No. “10” reversed is “01”, which writes as 1 — the digit strings do not match.

Do palindrome numbers score in RNGdle?

Yes. A full-string palindrome earns the Palindrome badge; a long palindromic substring can hit Pocket Mirror under family supersession.

RNGdle is a free browser game where you generate one random number from 0 to 1,000,000 each day. Instead of guessing words, RNGdle analyzes your roll for numerical patterns, awards badges, and scores EP (entropy points) so every daily number feels like a collectible result.

How does RNGdle scoring work?

RNGdle scoring adds EP from every badge your number unlocks. Badges in the same family supersede each other—only the highest-EP badge in that family counts—then your total EP ranks the roll from Trash and Common up through Rare, Epic, Anomaly, and Mythic.

How do you play RNGdle?

To play RNGdle, open the site and press GENERATE for today's official roll. Review the badges, check your EP and rarity tier, share the result if you like, then return after midnight for a fresh daily number.

What RNGdle badges can you get?

RNGdle badges cover mathematical and novelty patterns: perfect powers, consecutive digit runs, pairs and of-a-kind sets, palindromes, zero/void ladders, pi and e slices, plus meme exacts like Nice (69), Botanist (420), and Jackpot (777). New rolls can unlock many badges at once.

Is RNGdle a daily game?

Yes. RNGdle is a daily game with one official GENERATE per calendar day. After you roll, the next official number unlocks after midnight, which keeps each day's result unique and shareable.

What features are local in this RNGdle version?

In this RNGdle version, your daily roll, badge collection, lifetime EP, theme preference, and recent history are stored locally in the browser. You can play without creating an account; clearing site data resets local progress.

Palindrome Numbers

A palindrome number is an integer whose decimal digits are a palindrome: the digit string equals its reverse. Single digits count; leading zeros do not (we compare the number as normally written).

Formula

For digits d₀d₁…dₖ, require dᵢ = dₖ₋ᵢ for every index i.

How to check

Convert the integer to a digit string and compare it to the reversed string. Equal strings mean it is a palindrome number.

Example

12,321
12321 reversed is still 12321, so it is a palindrome. 12320 reversed is 02321 → 2321, so it is not.

In RNGdle

Palindromes are one of the most recognized digit patterns in RNGdle. A full-string hit scores the Palindrome badge; a long palindromic substring can also fire Pocket Mirror (same family — highest EP wins).

Palindrome — Reads the same forwards and backwards. (+50,025 EP)
Pocket Mirror — Contains a palindrome of 4 or more digits. (+2,124 EP)
