Most Common UK Lotto Numbers — Full Frequency Analysis & Odds
UK Lotto draws 6 main numbers plus a Bonus Ball, all from the same 1–59 pool, every Wednesday and Saturday. It has run the 6/59 format since October 2015, giving a long, consistent dataset to analyse.
UK Lotto main ball frequency
Across our full draw history, the five most frequently drawn main balls have been 39 and 33 (tied), followed by 11, 38 and 27, while 55, 50, 53, 51 and 56 have appeared least often. With 59 numbers and 6 drawn per game, each ball's expected share is roughly 10.2% of draws.
Notably, several of the least-drawn numbers cluster in the 50–59 range. That may simply be sample variance rather than a lasting pattern — visit our live UK Lotto statistics page for exact current counts, updated after every Wednesday and Saturday draw.
UK Lotto sum range
For 6 balls from 1–59, the mathematical range runs from 21 up to 339. In practice, the middle 70% of real draws fall between roughly 122 and 202, averaging around 162.
How the jackpot and "Must Be Won" rule work
UK Lotto no longer has a fixed jackpot cap. Instead, the top prize can roll over for a maximum of five consecutive draws before a "Must Be Won" rule forces it down to the next prize tier if nobody matches all 6 numbers. The minimum guaranteed jackpot is £2 million on a Wednesday and £3.8 million on a Saturday.
The Bonus Ball, drawn from the same 1–59 pool immediately after the main 6, only matters for the "match 5 + Bonus Ball" prize tier — it plays no part in winning the jackpot itself, which requires matching all 6 main numbers regardless of the Bonus Ball.
