From now on there will be only one draw per month done on the 1st Wednesday However, there could very well be spot draw from time to time, done on a random basis with only a short time to claim the prize and no redraw.
They could be for anything and done at any time with as little as a few hours to claim and as long as a couple of days.
These draws will be open to everyone who is registered in a current quarter.
