In both American and UK casinos the number of numbers that you select on a Keno ticket is nicknamed a spot. For example a player who marks a keno ticket and picks 8 spots on a $4 ticket would be playing a $4 8 spot ticket. If you choose 30 numbers at $1 each you would be playing a $1 30 spot ticket and so on.

In a uk online casinos there is usually a Keno lounge where you go to watch the numbers play out on a screen of some sort.  You usually fill out a piece of paper known as the blank keno ticket with the numbers of your choice and take it to a teller (sometimes called a writer) who then hands you a receipt, copy or computer print out of the numbers you have chosen.

At the bottom of the ticket there will also be a spot where you are obliged to write out how many numbers you have chosen and what the wager is. This is to prevent any disputes on sloppily marked cards. Many keno tickets are sloppily marked simply because there is so little time between keno callings in uk casino. Some keno lounges use brushes and India ink to confirm your receipt of the number chosen. It is always a good idea to verify the numbers you have chosen to play before you leave the teller window to avoid disputes. It is also a good idea to do this because if you win big, the casino will go back through their records to make sure that the numbers match.

Once you have your copy or receipt of the numbers you have chosen, you simply wait for the line up to die down at the teller. A casino attendant will declare the game “closed” and balls marked with keno numbers are dropped into a hopper and mixed. The numbers are displayed on a big screen or board as well as called out by a dealer as they are dropped out of the machine and could not able to get casino bonus.

If you have a losing ticket for a game and you want to play the same ticket for the next game, you don't need to mark numbers another blank ticket. You can just submit the losing ticket to the dealer along with your wager and you will be provided with another receipt. You can also do the same for a ticket that pays off. You are usually well taken care of in keno lounges as the staff is usually very well trained to ask you if you “want to play again.

It can’t be stressed enough that you must cash in your winning keno ticket immediately after the casino game is over. The rules about this vary from casino to casino but in the U.S. tax law requires winning tickets to be cashed immediately after the game or else this ticket could be declared null and void. This law comes from the fact that the casino could claim unclaimed tickets as some sort of tax write off.
