Up to January 31, 2013 the Eurojackpot lottery had a 'rolldown' clause: in case the jackpot is not won for 12 consecutive draws, the 13th draw will be subject to a rolldown whereby if no winner is able to match all 7 winning numbers, the jackpot is paid out to the next winning tier where a winner is available.

For the groups except the first one, the winning amounts are calculated nationally, and they can vary by country based on number of winners, lottery tax and other reasons.
