A bonanza is usually done going to the weekend starting on a Thursday and ends on a Saturday. If you buy your 2 + 1 tickets during a bonanza, you are automatically qualified for a mini draw to be done on the Sunday right after the weekend Bonanza. 10 names will be picked from the weekend buyers and each one wins 3 FREE TICKETS more valid for the same Big Ticket Draw. The same applies to the Countdown Bonanza except that it happens on the last 5 days of the month. Not all promos / months have a Bonanza.
