⚡ Unlimited Practice - roll as many times as you like

Roll a number. Uncover what's hidden inside it.

RNGdle turns a single random number into a hunt for primes, palindromes, repeats and rare numerical coincidences. This is unlimited practice mode - every roll uses the real badge and rarity engine, with no daily limit.

Guide

How RNGdle works

RNGdle is a daily random number game. Each day you get one roll to generate a random number from 0 to 1,000,000. Your number is analyzed for interesting patterns and properties, earning you badges and EP (entropy points). This unlimited mode lets you repeat the same process freely for practice.

Step 1

Roll

Press the button to generate your number. In daily mode you get one official roll per day; in unlimited mode there's no cap.

Step 2

Discover

See what badges your number earns based on its mathematical and visual properties - primes, palindromes, repeats and more.

Step 3

Collect

Build your badge collection over time. Rarer patterns are worth more entropy points.

Step 4

Show off your roll's badges and rarity tier to friends with one tap.

Rarity system

Number rarity tiers

Your roll's overall rarity is based on your total EP compared to all possible rolls, ranking your number against the full 0-1,000,000 range.

Badge probability

How badge rarity is set

Each badge has a rarity based on how likely it is to appear. Rarer badges are worth more EP toward your overall tier.

CommonMore than 10% of rolls

Uncommon1% - 10% of rolls

Rare0.1% - 1% of rolls

Epic0.01% - 0.1% of rolls

Anomaly0.001% - 0.01% of rolls

MythicUnder 0.001% (1 in 100,000+)

Badges to discover

FAQ

Frequently asked questions

What is RNGdle? +

RNGdle is a daily random number game. Each day, you get one roll to generate a random number from 0 to 1,000,000. Your number is analyzed for interesting patterns and properties, earning you badges and EP (entropy points).

What is RNGdle Unlimited? +

RNGdle Unlimited is the free-play practice mode. It uses the exact same badge and rarity logic as the daily game, but you can roll as many times as you like to learn patterns and build your badge collection without waiting for a new day.

How is number rarity calculated? +

Your roll's overall rarity is based on your total EP compared to all possible rolls. Tiers run Trash (bottom 1%), Common (bottom 50%), Uncommon (top 50-25%), Rare (top 25-10%), Epic (top 10-5%), Anomaly (top 5-1%), up to Mythic (top 1%).

How is badge rarity determined? +

Badge rarity is determined by probability: Common is over 10% of rolls, Uncommon is 1-10%, Rare is 0.1-1%, Epic is 0.01-0.1%, Anomaly is 0.001-0.01%, and Mythic is under 0.001% (roughly 1 in 100,000 or rarer).

Does practice mode affect my daily leaderboard? +

No. Unlimited practice rolls are kept separate from your daily roll and are stored locally on your device so you can experiment freely.

Is my data stored anywhere besides my browser? +
