Keno Experiment is an extended version of the Keno lottery game. In Keno Experiment, you may set an amount of numbers to be picked at random for the next round, or you can play 5 rounds with completely random selections.

The playing area of Keno Experiment contains numbers ranging from 1 to 80. You pick numbers just by clicking on them. Choose anywhere between 2 and 10 numbers for every round. Once you've made your selection, click Play One to begin the round, or Play Five to play 5 rounds in a row with the numbers you've chosen.

You may deselect a number by clicking on it, or you can remove all selections by clicking the Clear button.

Under the main playing area is a row of buttons marked 2 through 10, plus Random Pick and a checkbox "Pick new numbers before each round". These allow you to play with numbers chosen at random. Set the amount of numbers to be chosen for the next round by clicking on the corresponding button - you may play between 2 and 10 numbers each round. Click Random Pick to generate the selection, and click one of the Play buttons to start the spin.

If you have clicked on the Random Pick button without setting the amount of numbers, it will automatically be chosen.

The "Pick new numbers before each game round" checkbox is used for playing 5 rounds in a row. A new random selection will be made before each round.

There are 4 screens to the right of the game window :
Payouts - The payout will depend on how many numbers you've selected. This screen displays the amount of hits you need to win, and how much you will win in each case.
Bet - This screen displays your bet amount.
Results - This screen displays the amount of hits you had in the last round. In a 5-round game, it shows the results of all the rounds.
Win - This screen displays how much you won for this round.

Just above your account balance is the bet amount pad. Click the arrows to change your bet amount, ranging between 0.25 and 5.
