For some time I have been intrigued by the appeal of scratch cards. Of course they offer the chance to win large sums of money, in some cases, in excess of £1,000,000, but this seems to be a pretty remote possibility. Other cards with smaller prizes seem to have gained in popularity, even when the prize is as little as £100. I've looked at other review sites, and it seems that the average return on your speculation is around 60%. I want to try to increase this return if possible. Obviously this can't be done by just scratching cards and relying on luck.
