Name of certain "tile" game design

I can’t for the life of me figure this out. what type of game that has “tiles” → click the tile-> menu pops up-> choose what type of “thing” you want to build on said tile-> it builds. then you can buy more tiles, delete/sell the “thing”, etc.

any youtube video(s)?
forum thread?
text tutorial?

Do we win something if we get it right like one of those tiny Unity stickers?

RTS?
