ive only played and and decs a half dozen times at the pub.. i took the big gamble the first 3 times i got a mystery and it went to lose. so i never took it again.
was in the pub last week with a friend, first board i got to mystery and gambled and lost as usual. my friend insisted i took the big gamble. next board he reached over and hit big gamble... and as im complaining to him it stops on jackpot.
funny eh.
