[sharhelia]

Hi

i have never done anything in open gl yet. now i have a game in which there will be digging area. user can swipe one time to remove one layer of sand from the digging area to search for hidden stones, and if he click one more time more sand will be removed, and if he swipes for third time on the same area he will be shown stone if he find one otherwise blank area where he can not dig any more]. so how to do this
please give me some idea. is open gl the only way to do so or imageviews can be used in place ?
i dont know how to start for this view.
please help me guys

any code or helpful links will be much appreciated,

and i dont have any idea how to go for these three layers

thanks in advance.

happy coding
