It is almost impossible to figure out the algorithm of a computer game; at least you need to have a fat wallet to understand some strategy. It is unlikely that there will be such a daredevil who will not spare any effort or time to spend money regularly losing. Trying your luck is always fun, of course, but it is stupid to risk throwing money away. It is always better to make real bets on the sport you understand and have at least experience for future bets if you fail to win. In virtual bets, it is simply unrealistic to understand the principle of winning.
When it comes to virtual sports games, every gambler needs to be careful, because relying on gambling might not be profitable for them, as winning a bet is based on a hundred percent (100%) of luck. However, there are many virtual sports games and the gambler needs to understand the kind of virtual game he's betting on before wagering. Not having any clue about the game one is playing will also result in significant losses. Also, always spending money on gambling might not end well, as a gambler who's always gambling might become addicted to gaming/gambling in the near future.
Moreover, real bets (like real sports games) are the easiest to understand. Although one still needs to be lucky before he or she can win, it's easier to understand it as you can watch how the games play at your own comfort. IMO, only those that need urgent money gamble regularly on virtual games, because it doesn't take long to start, and it doesn't stay long to end.
