FAQ
Does playing the most common Thunderball numbers improve my chances?
No. Each draw is random. Past frequency has no effect on future draws.
Where does this data come from?
From aggregated draw history published by the National Lottery and third parties like Lottery Stats.
Why do some numbers appear more often?
Random variation. Over very long periods, frequencies tend to converge toward the theoretical average, but short and medium-term spikes are normal.
Is the Thunder Ball drawn separately?
Yes. It comes from a separate pool of 1–14. Its frequency is tracked independently from the main 5 numbers.
Can I see Thunderball stats on Fetix?
Fetix currently focuses on UK Lotto and EuroMillions. Use Lottery Stats or National Lottery for Thunderball data.
Why is the spread tighter for main numbers (2.04–2.12%) than for the Thunder Ball (7.05–7.31%)?
The Thunder Ball pool has only 14 numbers, so each one carries a larger share of the total draws than any single number among the 39 main balls—naturally widening its relative spread.
