Consistent with a fair draw

Chi-square 51.2 against a 66.3 threshold at 95% confidence, over 50 numbers. The spread sits well inside what an even draw produces. One fair draw in twenty crosses that line by chance, so a single reading either way is a prompt to keep watching rather than a finding.

Is a number ever “due”?

11.9%of numbers came up again in the very next draw
12%is how often any number comes up at all

Measured across 1194 number-to-next-draw pairs in this lottery’s own history. Those two figures being the same is the answer to both “it’s hot” and “it’s due”: the machine has no memory of last week.

  • Over the last 200 draws, 8 came up 38 times and 37 came up 14. A fair draw would average 24 each, and a spread this size is what randomness looks like at this sample size.
  • The full spread scores 51.2 on a fairness test that would need to exceed 66.3 before the draw looked biased. It does not. This is evidence the draw is even — not a reason to prefer any number in it.
  • A number that came up in one draw came up again in the next one 11.9% of the time. Any number at all appears 12% of the time. Those two being the same is the answer to "is it hot?" and to "is it due?" — the draw has no memory of what it did last week.

Every draw is independent. Nothing on this page makes any number more or less likely to come up next — it describes what has already happened, and shows that the draw behaves the way a fair one should.
