How UK 49s Prize Tiers Work
While the jackpot requires a perfect match, UK 49s awards prizes for partial matches as well. Matching 4 of 6 main numbers is far more likely than matching all 6, which is why lower-tier prizes are smaller but won more frequently. The Booster adds complexity — since it is drawn from a separate pool of 49 numbers, it effectively multiplies the number of possible outcomes and creates additional prize tiers.
