Once the game of keno starts, out of the eighty numbers available, only twenty of them will be drawn and depending on that only it will be decided whether you won the money or not and if yes, by what amount.
There are many other factors also which decide the winning percentage and the winning amount but since it is a game of chance and not strategy, luck is always on the driver’s seat. Before you actually play for real money, it is assumed that you play for free to gain a knowledge of the know how and loopholes if you can detect any.
