Frequently Asked Questions
How do I simulate a Mark Six draw?
Set the count to 6, enable "No duplicates," then click Generate. Mark Six draws 6 numbers from 1-45, and this produces exactly that format — with every combination having an equal chance.
What are the odds of matching all 6 numbers from 45?
A 6-from-45 draw has 8,145,060 possible combinations, so any single line has roughly a 1 in 8.1 million chance of winning the jackpot.
Can I type a custom count, like 6 numbers between 1 and 45 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 45 range?
Exactly 45 (counting both 1 and 45). Each has an identical 1-in-45 chance (2.22%) of appearing on every draw, independent of previous results.
