Some countries are not so good at enforcing this or rely on the games developers or publishers to tell them what is in the game in order to give it a rating.
The most famous example of this system "going wrong" was when someone discovered the "Hot Coffee" codes were still hidden away in GTA and the ratings folks flipped their lid as they hadn't been told about the evil child corrupting sex in the game (because killing people, theft and violence is ok but think what would happen if a 15 year old knew about sex!).
The good news is if they do have a game corner fun, exciting minigames based on skill or logic like voltorb flip would populate it rather than dull, boring chance based games like the slots.
