KENO

There is a large Keno board with numbers from one (1) to eighty (80).
In a basket, wire cage or plastic bubble there are balls numbered from one (1) to eighty (80).
 Twenty of the balls are drawn randomly and it is up to the player to predict which numbers will be drawn and to place a bet on as many as fifteen of those numbers.
A player may choose to bet on any number of ‘spots’ (up to 15) for the price of one ticket.
 The price of the ticket is not dependent on the number of spots chosen.
 The more spots the player correctly predicts the higher the payout.

Keno's interface is quite simple.

Use the Chip Size menu to change the amount you are wagering per ticket.

The Keno Ticket is the large grid of numbers that dominates the play area of the Keno game.
On it you will find the numbers 1 through 80. Left click on the Keno ticket to select a number.
 It will be highlighted. To deselect the number left click again. You can select up to fifteen numbers.

The Clear button removes all currently selected numbers.

The Undo reverses the effects of the last Clear.

Press the Play button to start a game of Keno once you are finished selecting your numbers.
