Lotto Must Be Won Draws are special events where the jackpot rolls down to a lower prize tier if no one can match all the six main lotto numbers. During these draws, thousands of lotto players can win bigger prizes than usual. This is due to guaranteed jackpot win in case of roll down.
Camelot, the UK Lotto operator, introduced these special Draws in November 2018 when the jackpot has rolled over five times. In some occassions, Camelot may also schedule must-be-won draws for special occasions and events. During festive seasons like Easter or Christmas, it is common to witness these special Must-be-won draws.
