What is a Cascade draw?
A cascade draw takes place after three consecutive draws without a Group 1 Prize winner.
The Jackpot does not snowball beyond the fourth consecutive draw. If there is no Group 1 Prize winner at the end of four consecutive draws, the final jackpot amount (38% of the fourth draw's prize pool plus snowballed amount from the three preceding draws) cascades, i.e. it will be paid to the next prize group with winner(s) and shared equally.
