One number. One roll. See what makes yours unusual.
One roll per UTC day

How This RNGdle Game Works
Roll one number between 0 and 1,000,000. We scan its digits and mathematical properties, award every matching badge, and add their EP values into one score. Common patterns earn a little; unusual combinations earn more.
RNGdle is a game of luck, not a reaction-time measurement. Want a skill-based challenge instead? Try the Number Hunt or return to the reaction time test.
RNGdle FAQ
What is RNGdle?
RNGdle is a quick daily number game. You roll a number from 0 to 1,000,000, then the game finds interesting patterns in it and awards Entropy Points (EP).
How do you play?
Press the roll button once. Your number is checked for patterns such as primes, palindromes, repeated digits, sequences, and internet-famous numbers. Badges stack, so one roll can match several patterns.
Can I reroll?
No. Your roll is saved in this browser until midnight UTC. That single-roll rule is what makes a lucky number feel special.
Is this the official RNGdle?
No. This is ReactionTester’s independent RNGdle-style game with its own badges and scoring. It is not affiliated with rngdle.com.
