Most bets in Keno are designated by the number(s) you pick. For example, a “one-spot straight ticket” is a bet on a single number. A “two-spot straight ticket” is a bet on two numbers. The amount of money you can bet in Keno depends on the type of bet you’re making. These bets usually range from $1-20 for straight tickets.

The most common bet is a five-spot straight ticket at a price of $1, in which five numbers are picked. For this bet to win, three of the numbers you pick must come up on the balls. This particular bet pays even money if you pick three numbers right. If you pick four winning balls, you are paid off at 9 to 1. If, in this example, you guess all five balls right you’ve hit the jackpot, paying 800 to 1.
As another example, the payoffs for a common $2 bet (in this case, a 10 spot straight ticket) are shown here:

Catch: Win:
10 50,000
9 8,000
8 2,000
7 260
6 40
5 4

In addition to straight bets, other types of bets are available. These include specials, the edge, top/bottom, and left/right bets.

The specials bets include four-, five-, and six-spot specials. When you bet on 4 to 6 numbers, a Specials checkbox appears in the Spots box on the Keno ticket. Click on the checkbox to change your ticket to a specials bet. Specials bets are more expensive to place, but pay at better odds than a standard four- to six-spot straight ticket.
The edge bet selects all the numbers around the edge of the Keno ticket as winning numbers.
The top/bottom bet is a bet that a high number of winning numbers will occur in the top or bottom half of the Keno ticket. No spots are marked on the ticket. Instead, you are betting that there will be many more numbers picked on either the top or bottom halves of the ticket. The greater the imbalance between top and bottom, the higher the payoff.

The left/right bet is a bet that a high number of winning numbers will occur in the left or right half of the Keno ticket. No spots are marked on the ticket. Instead, you are betting that there will be many more numbers picked on either the left or right halves of the ticket. The greater the imbalance between left and right, the higher the payoff.
