Well, you don't really open ads, you click on them.
You choose the correct picture after clicking on the ad (picture of a cat).
Then you wait for the timer to run down.
I see you have been a member for less than one month. It looks like you
have earned some money from clicking on ads so not really sure what you
are asking.
No one can help you win in the clixgrid and what you earn, for the most part
is up to the work you do.
