Keno Betting Rules
Do not forget that most casinos would allow you to play a minimum total of four numbers or a maximum total of ten numbers on one keno ticket. Each number you mark on a keno ticket is known as a spot. Thus, if you pick a total of ten numbers to play on your keno ticket, you are playing a 10 Spot keno game.
Each time that the casino closes its keno counters to randomly draw 20 numbered keno balls up until it displays the winning numbers on the keno screens is considered one round of a keno game. A round of keno is known as a keno race. Many casinos offer multi-race keno, in which case you are allowed to play a number of consecutive keno races at a given time.
The minimum bet in a keno game is usually $.05. In fact, some casinos allow no lower than a $1 bet, or even impose a minimum bet that is higher than a dollar. Casinos always provide information about their own keno payoffs and the various keno tickets you can play. Find the casino's keno brochures to find out about them, or ask the clerks at the keno lounge counters.
You may play as many keno tickets as you wish. The amount of money you can win is dependent upon the type of keno ticket you played and the number of spots your keno ticket caught. In a keno game, you can win as much as $50,000 on a $1 wager.
Keno Betting Tips
From The Wizard of Odds, here are a few points to ponder in terms of computing probabilities in a game of keno. You can use Excel and the like.
The probability of matching x numbers, given that y were chosen, is the number of ways to select x out of y, multiplied by the number of ways to select 20-x out of 80-y, divided by the number of ways to select 20 out of 80.
The number of ways to select x out of y refers to the number of ways, without regard to order, you can select x items out of y to choose from. This function may be represented as combin(y,x).
Generally stated, combin(y,x) is y!/(x!*(y-x)!). For those of you who are unfamiliar with the factorial function: n! is defined as 1*2*3*...*n. For example: 5!=120. Thus, the number of possible five card poker hands would be combin(52,5) = 52!/(47!*5!) = 2,598,960.
Ergo, the overall general formula for the probability of x matches and y marks is: combin(y,x)*combin(80-y,20-x)/combin(80,20).
To test this formula, let us try to find the probability of getting 4 matches given that 7 were chosen.
This would be the combin(7,4) multiplied by combin(73,16) divided by combin(80,20). combin(7,4) = 7!/(4!*3!) = 35. combin(73,16) = 73!/(16!*57!)=5271759063474610. combin(80,20) = 3535316142212170000. Thus, the probability is: (35*5271759063474610)/3535316142212170000 =~ 0.052190967.
To determine the expected return of an overall number of picks: take the dot product of the return and the probability for each number of winning catches. For example: the pick 5 at the Atlantic City Tropicana pays 1 for 3 catches, 10 for 4, and 800 for 5. Thus, the return is: 1*combin(5,3)*combin(75,17)/combin(80,20) + 10*combin(5,4)*combin(75,16)/combin(80,20) + 800*combin(5,5)*combin(75,15)/combin(80,20) = 0.72079818915262.
