Marketers always use some strategies to offer their customer something seems really attractive, but actually the truth is so different.
When playing games, especially the random ones, probability is a big issue. The game designer needs to calculate the outcomes carefully to make sure the game is profitable from his or her point of view. But all the players want to win as well. If their expected value is below what they pay for game, they won’t play. It is like a zero-sum game, someone must lose in order to make others win. So the designer better to take a serious consideration about how to make the game looks profitable for the players while he is the winner actually.
So, be careful, players and buyers.
