How do I Pick object by overlapping and by distance between two sames objects ?

Hello everyone,

I try to make puzzle game like match 3 but more simpler.

I make this simple script, but when I launch it every green block destroyed.

I want to destroy green block if it's touching same more than 3 time, and only this specific block.

I try to do this with invisible object and say is overlapping this area. It's work but I have to put this area everywhere.

I try to do whit distance between two block but he did'nt work.

I don't know if my question is understandable, but I just want to destroy green block if if he hits more than three blocks.

Thanks for helping me !

The most common solution is to use a family. Add Vert object to a family and then you will be able to use conditions like "Vert Overlapping VertFamily" and reference both instances separately in the same event.
