4D Number Generator
Random 4D numbers in one tap, with optional filters. Everything runs in your browser — nothing is sent to our servers except anonymous usage counts.
10,000 of 10,000 numbers match your filters.
Your numbers
Numbers are drawn with your browser's cryptographic random generator, evenly across every number that matches your filters. They are not predictions and do not improve your chances — each official draw is independent and random.
How it works
The generator first lists every number from 0000 to 9999 that fits your filters, then picks from that list using your browser's cryptographic random number generator. Every eligible number has exactly the same chance of being chosen, and each pick is unique within a set.
- No repeated digits keeps numbers like 3907 and removes ones like 1123.
- Odd / even balance keeps numbers with exactly two odd and two even digits.
- Include and exclude let you require or ban specific digits.
Every 4D draw is independent and random. Past frequency, “hot” or “cold” status and generated numbers do not change the odds of any number being drawn. Statistics here are for information only.
Questions
Are generated numbers more likely to win?
No. Generated numbers are random picks, exactly like choosing numbers yourself. Official draws are independent and every number has the same chance.
Where are saved numbers stored?
Only in your browser on this device (local storage). We never see them, and clearing your browser data removes them.
Why do filters reduce the available numbers?
Filters remove numbers that don't match. For example, blocking repeated digits leaves 5,040 of the 10,000 possible numbers.
