A mobile game that shoves advertisements up your face to get them money. These types of games are made by big mobile game studios that overload you with idle games and unoriginal ideas. Example: VOODOO.
Voodoo uses a simple art style. Then, they pay their artists (if they even have any) by copying those exact models in every game, to be more cheaper.
"Hey what are you playing?"
"This really greedy Mobile game. I can't stop getting ads."
