^ Unfortunately we can't per the rules Mod Kalayasaid: If, by mistake, two or more of the same number is posted in a row by different players, those 'duplicate' numbers may not be counted as a new number. For instance, if two 10's were posted, the next player may not continue at 12. Instead, he or she must continue at 11.
13 is not unlucky and is one of my favourite numbers but maybe that is because my b.day falls on the 13th of a month. Actually....Maybe that is unlucky lol.
