O.M.G.
Some people need guiding through life, don't they? Camelot had to remove one of their lottery scratch cards from sale because customers couldn't understand if they had won or not.
Basically, the card would display a temperature, and in order to win, the player had to scratch off and reveal a temperature lower than the one displayed. Sounds easy enough, right?
Apparently, many players were too confused as to whether or not they had won, because they could not grasp that the sub-zero temperature of -5 was higher than -6!!! I am rubbish at maths but c'mon, folks!!!!
