Keno is very easy and the interesting thing is that you can win big sums of money with small wagers.  The player guesses numbers that will win, they mark them in the keno ticket and they make a bet on that number.

Whether you bet just one number or more numbers the payout is going to be appropriate for the numbers you bet.  There is no need that you have to bet 10 numbers at a time. However, a minimum of 4 numbers should be marked.

If you are not comfortable betting 10 numbers, you can choose to bet in just 4 or a bit more numbers as suited for your bankroll efficiency.

Once you mark the numbers on the keno tickets, you can draw 20 balls from the keno barrel. The numbers on the keno ball and the numbers that coincide with your spots are displayed on the leader board.

The minimum bets per spot differ between casino sites offering keno.   If you were in a brick and motor casino, you would pick up a crayon and mark them on the tickets; however, in an online casino everything is graphical click marking.

When you play in a brick and motor casino, you have to keep the ticket safe, produce it to the cashier and collect the money you win. However, in an online casino your payment is credited automatically to your money account.

Plan your money strategically because you do not want to play more than what you can afford.  The results are random and past results have nothing to do with the present numbers.
