The possibility of the rich person to make the big winning because of their back up money for the further game.The gamblers who want to make huge money should hold the money for the backup even after the loss.Many poor gamblers will lose the hope and money in the gambling site.So the poor gamblers don’t have any backup money for the further game.This was biggest drawback for the poor gamblers,even after earning good strategies with the loss.The poor gamblers won’t have money to make the continuous winning.So the gamblers who have huge money will create more money from the same gambling site.
Sometimes it's not even about having more back up money but a lot has to be done with strategy, when you have got a very good strategy and risk management even with your little bankroll, you still be able to stay long enough in the game but without a good risk management strategy, it's very obvious you will not last long gambling before you go bankrupt.
The Rich gambler usually have stake but a poor gambler usually low or stake with the minimum amount allowed at a time so the difference is usually with the amount they are able to stake at a time, the rich may have a very big bank roll and divides it into several portions and stake accordingly but a poor gambler with no strategy may put all his bankroll at once so he will be able to equate with the rich guy and when they loose he's kicked out while the rich still continues because he's got a strategy with which he continues to stay in the game as against that of the poor guy without a strategy but if the poor guy divides his little bankroll in to several portions then he could stay as long as the rich guy too.
I am wondering why Westinhome deleted his comment, or was that the work of a mod, I don't think so..
But back to the discussion, what you said is right, though very different from what I understand Westinhome to be saying, Westinhome is actually talking about the ability for gamblers to test a game in their fun mode, which is often for free, before moving to play the same game in their normal play mode which requires real money, he is saying that doing this will help a gambler learn much about a game and how to win it before the gambler commits real money into the game.
I was going to partially agree with this, on the grounds that this feature is only available on slot and in-house games, and it is also very limited to some casinos or a few casinos rather, and the ultimate reason again, I feel this strategy does not add any value to a gambler is because, from my personal experience, playing a slot game in fun mode, is completely different from playing same game in their normal paid mode, a game one easily wins in fun mode, can be so difficult for the same player to win same game in their paid mode, because fun mode and paid mode of slot and in-house games are programmed differently.
