At a glance
- The UK Lotto jackpot is won on about 1 draw night in 6: 188 of 1,144 nights since the game moved to 59 balls in October 2015 (16%).
- The rate has held steady: 17 of 104 nights in the last 12 months, and 5 of 31 evenings since the New Lotto started on 10 June 2026.
- Before October 2015, with 49 balls, the jackpot went on 77% of draws. The bigger ball pool is why rollovers are now the norm.

Overview
The UK Lotto jackpot (Match 6) has odds of 1 in 45 million per line, per round. Since 10 June 2026 a £2 ticket plays both rounds of the evening, so it holds two chances at the jackpot rather than one. With millions of lines sold per draw, the jackpot is won regularly—but not every draw. Rollovers occur when no one matches all 6. Must Be Won draws guarantee a winner when the jackpot hits the cap.
Jackpot frequency depends on ticket sales and luck. Past frequency does not predict the next draw.
Important
Your odds remain 1 in 45 million regardless of rollovers. A rollover does not make the jackpot "due".
Typical jackpot win rate
Typical jackpot win rateThe odds are 1 in 45,057,474 per line, per round. Since 10 June 2026 the evening's jackpot is shared across the two rounds: it is won as soon as a Match 6 appears in Round 1 or Round 2, which mechanically makes a rollover less likely than under the single-draw format. So far the jackpot has gone on 5 of the 31 New Lotto evenings (to 23 September 2026) — still too few to measure a difference. Fetix records the winning round for each evening.

Rollovers and Must Be Won
When no one matches 6, the jackpot rolls over. It continues until won or until it hits the cap. At the cap, the next draw is "Must Be Won"—if no one matches 6, the jackpot is shared among lower tiers. The jackpot is always won on that draw.
See UK Lotto Must Be Won for details.
Historical spikes
Some periods see multiple rollovers (jackpot grows). Others see quick wins. This is randomness—ticket sales and the random draw interact. No pattern predicts when the next win will occur.
