Frequently Asked Questions
How do I simulate a Keno draw?
Set the count to 20 and enable "No duplicates," then click Generate. This draws 20 unique numbers from 1-80 — the exact format of a standard Keno game.
What are the odds in Keno?
Keno odds vary by how many spots you pick. Matching all 20 drawn numbers when you picked 20 is astronomically rare (about 1 in 3.5 quintillion) — which is why Keno jackpots are so large.
Can I type a custom count, like 6 numbers between 1 and 80 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 80 range?
Exactly 80 (counting both 1 and 80). Each has an identical 1-in-80 chance (1.25%) of appearing on every draw, independent of previous results.
