By the way, I would like say one very important thing. In this world, things don't happen by chance as such, and definitely not to the extent of what the mass think of. While there might be some randomness involved, be it video games, casino games, video casino games or simulated casino games, lotto or lottery... there are reasons to why this or that has occurred besides randomness. In fact, randomness might contribute very little relative to what people might think of. But, due to their beliefs or whatever there is, they think such and such things has occurred due to luck or chance. In the case of video games or machine games, many things have been programmed to occur. A particular thing will occur when it has to occur, that is when certain criteria has been satisfied, unless there is a malfunction. It is only a matter of being there on that game or machine at that time; this where randomness or 'chance' may be said to come into play.
Concerning other things that happen in life, randomness has even less contribution to it. In fact, it might be virtually none existent in most cases, but people believe this or that has occurred because of 'luck' due to their 'blindness' or beliefs.
