A few things have changed in Keno since most Keno games have computerized in recent years. One of the most important changes as far as the player is concerned is the inside ticket.
When Keno tickets were written with a brush, the inside ticket was the ticket which the player presented to the writer. The writer would make a copy of the ticket, which would be given to the player, while the inside ticket would be kept at the Keno game. It would usually be photographed and stapled into a "book" before the call of the game. In the case that the Keno writer made an error while copying the ticket, the inside ticket was the official ticket for computation of any winners on that game.
So what has changed? For all intents and purposes, there is no such thing as an "inside ticket" at a computer Keno game. If you read the rules closely at most computer Keno games, you will see language such as "We pay according to the ticket that is entered into the computer Keno system" or some such. This means that if a writer makes an error when entering your ticket, the casino is not liable to pay on your original ticket as they did on a brush game.
Many casinos will pay out small winners in instances like this, just for customer good will, but few if any casinos will pay out large winners on mismarked tickets. Although computer Keno systems will re-write Keno tickets accurately, it is vital that you check your tickets carefully every game. If you don't, you are risking financial tragedy. Tickets are particularly vulnerable to mismarks 1) the first time played, 2) whenever any thing such as price or ways are changed, or 3) when changing from single game to multi-race or vice-versa.
You should check your tickets without fail any time such a situation arises. Although all the Keno systems on the market have the capability to recall tickets and change one item such as price or ways, while leaving the spots and the groups intact, some Keno writer will invariably re-write the ticket manually instead, thus increasing the possibility of errors.
There is one other situation that arises that the player cannot be aware of, but does lead to mismarked tickets. A Keno writer may write a ticket twice, void out both tickets, and then re-write one of them manually. In this case, the customer has made no changes in his or her ticket, and therefore might assume that the system will produce a perfect copy. This is why you must check your tickets every game to be safe.
One of the drawbacks of the computer Keno system is its very accuracy. Because of it's accuracy, both players AND Keno writers don't check their tickets as well as they used to. Thus an error, once made, might be propagated for ten, twenty or more games before it is noticed. By then it might be too late! PLEASE CHECK YOUR TICKETS!
Well that's it for this week. Good luck! I'll see you in line!
