Not all games are manually reviewed.
There is no official explanation of the algorithm that passes a game to manual review.
If your game does not appear, it is because it is waiting to be manually reviewed and the only thing you can do is wait.
how long does it take?
Normally between a few hours and a couple of days, but can last up to 2 or even 3 weeks.
Normally if you ask before two weeks, you will be asked to wait.
