Allwyn, operator of the UK National Lottery, will introduce a two-round Lotto format on June 7, 2026. Every £2 Lotto line will carry two chances to win, with the ticket price and the number of balls unchanged. Two separate draw machines will each produce six main balls and a Bonus Ball, so a single line can win in the first round, the second round, or both.
The change improves the odds of winning any prize from about 1 in 9.3 to roughly 1 in 4.9, and Allwyn projects it will lift the number of millionaires created each year from around 140 to about 345. Jackpots will start at £2 million and can roll over up to five times before a must-be-won draw. The overhaul is part of a wider summer rollout that also includes a new Powerball game for the UK market.
