A data-driven look at which balls have appeared most — and least — since the 1–59 format launched in October 2015.
Since the UK National Lottery Lotto expanded its ball pool from 49 to 59 numbers in October 2015, there have been 1,099 draws. With six balls drawn each time, that's 6,594 individual ball appearances to analyse. Not all balls have appeared equally — here's what the data shows.
These ten numbers have appeared significantly more often than the mathematical average of around 112 appearances per ball:
| Rank | Number | Draw count | vs average |
|---|---|---|---|
| 1st | 42 | 153 | +37% |
| 2nd | 38 | 148 | +32% |
| =2nd | 54 | 148 | +32% |
| 4th | 37 | 145 | +30% |
| =4th | 39 | 145 | +30% |
| =4th | 52 | 145 | +30% |
| =4th | 58 | 145 | +30% |
| 8th | 8 | 143 | +28% |
| 9th | 20 | 142 | +27% |
| =9th | 36 | 142 | +27% |
Number 42 is the clear leader, appearing 153 times — more than once every seven draws on average. Numbers 38 and 54 are joint second at 148 appearances each.
At the other end of the spectrum, these numbers have appeared notably less often:
| Rank | Number | Draw count | vs average |
|---|---|---|---|
| Least drawn | 26 | 116 | −4% |
| 2nd least | 21 | 117 | −4% |
| 3rd least | 25 | 118 | −3% |
| =3rd | 55 | 118 | −3% |
| =3rd | 44 | 118 | −3% |
| 6th | 35 | 119 | −2% |
| 7th | 30 | 121 | −1% |
| =7th | 43 | 121 | −1% |
| =7th | 24 | 121 | −1% |
| =7th | 1 | 121 | −1% |
The difference between the most and least drawn ball is 37 appearances (153 vs 116) across 1,099 draws. That sounds significant, but spread across over a decade of draws, it works out to roughly 3–4 extra appearances per year for the hottest numbers. In a truly random system, we would expect some variation — and this level of spread is broadly consistent with normal statistical variance.
Statistical note: With 59 balls and ~112 expected appearances each, a spread of ±20 from the mean is well within normal variance for a random process over 1,099 draws. The differences we see are real, but they are not necessarily meaningful for prediction.
It's worth noting that 42 topping the frequency charts could be pure statistical noise — or it could reflect a subtle pattern that will persist. Without access to the draw machine's physics, we simply can't know. What the data does tell us is that if you had played number 42 in every draw since October 2015, it would have appeared on your ticket 153 times — more than any other number.
All of this frequency data powers the five strategies available in our predictor tool. The Hot Numbers strategy draws exclusively from the top 20 most-appeared balls. The Overdue strategy focuses on the least-drawn. The Balanced Blend and Frequency Weighted strategies use the full dataset with different weighting approaches.
