A lot of gamblers have their superstitions, wendilla. Mine is that i only have a punt when there is a 'y' in the day. My main source of winners stems from studying statistics and it would be very interesting to discover just how many jackpot winners have had encounters with black cats:-)
Of course, we are all aware that the only way to scoop the jackpot is to totally forget your regular numbers, you know, the ones you have used for the last 21 years, and just use any old numbers or a lucky dip (or, as i call it, a dip). And you cannot be sure you have won unless you first believe you only have 3 numbers; then on second glance you discover you have four. It is only when you have shown your ticket to your partner/parent/friend/neighbour/goldfish for them to check that you realise that you have the jackpot. If i don't win, i hope someone else does:-) Best of luck.
