You can choose from 2(minimum) to 10(maximum) spots on the keno card by touching the numbers desired. Marked spots are yellow. Touch the number again to clear the marked number/spot. There is a wipe-all feature as well. After all set, you can hit the play button and then 10 balls will appear, and then you will have the option of either raising or keeping your current bet value. Each ball that matches a marked spot is a hit.
