Recently I noticed that some casinos offer an option they call 'play for fun' and 'real play', which are also the same things as 'demo mode' and 'real funded account play mode'.
"Fun Play" appears to be an attractive point of investment because the "Fun Play" algorithm, designed by their developers, features. Here, you can only lose more and more money or not win majorly of the time. Very little time they lose the practice mode. On the other hand, winning the demo mode, many people invest their real money and lose, lose, and cown-down lose. It's the features of casinos.
