A double bottom occurs when a lotto number, which has not hit for several drawings, hits, then loses an equal amount of drawings and hits again. For example, a lotto number could skip eight drawings, hit, then skip another eight drawings and hit again. The second skip that forms the Double Bottom can be one off, that is, in this case, either seven, eight or nine, and still conform to the Double Bottom pattern. A lotto number can be bet anticipating a Double Bottom to occur. Use the Drawings Since Hit Chart, especially the abbreviated sub-chart, in Advantage Gold to look at these lotto trends.
