How do I Space randomized Objects

I am working on this game:

https://www.scirra.com/arcade/other-gam ... -game-6075

I want a way of spacing the randomized taps. Can anyone help?

Here is a post that should be similar (lower half)

Thanks you for your help. I read the post, but, it does what my game already does.

The problem is, the taps overlap sometimes. I need help with randomly positioning the holes in the wall, such that, the taps do not overlap when they are spawned.

You should take a look at the second half of the link above

Here there are two post that give you some clues how you could achieve this.

Basically with a loop, Spawn points or is overlapping
