Frequently Asked Questions
Can I use this for UK Lotto number picks?
The classic UK Lotto drew 6 balls from 1-59 (updated from the original 1-49). This 1-49 range still matches many international lotteries. Generate 6 unique numbers by setting count to 6 and enabling "No duplicates."
How many possible combinations exist in a 6-from-49 lottery?
There are exactly 13,983,816 possible combinations when choosing 6 numbers from 49 — meaning each ticket has approximately a 1 in 14 million chance of matching all numbers.
Can I type a custom count, like 6 numbers between 1 and 49 at once?
Yes — the "How many?" box accepts any count from 1 to 1,000 (type 6, 25, 500…), and the quick buttons fill common values. Turn on "No duplicates" when every number must be unique.
How many possible results are there in the 1 to 49 range?
Exactly 49 (counting both 1 and 49). Each has an identical 1-in-49 chance (2.04%) of appearing on every draw, independent of previous results.
