» Keno Combinations

In modern casinos "Keno runners" walk around calling "keno!" and offer to carry players' wagers to the keno booth for processing. The players give the keno runner the "inside ticket" and the wager payment. A keno wager form filled out by the customer is called the "inside ticket". After that he takes the wager and that ticket and carries them to the counter. The keno runner returns with an "outside" ticket, which is the official wager receipt. It is incumbent on the player to check the ticket for errors before the game balldraw is drawn. Any errors not corrected before the balldraw begins are not normally rectified.
When all the 20 numbers are known, the winning tickets are paid. The payouts differ in defferent casinos. If you have, for example, a four-spot ticket, you are paid 1:1 if 2 numbers hit, 1:5 if 3 numbers hit and 1:120! if all the 4 numbers hit. But in another casino, the three-number hit might pay and all four 5, and in another the payoffs might be and 0. Because of the variation, no payback percentage is common enough to be called average. Paybacks range from below 70 percent to more than 80 percent.
