BitLife is a life simulation game where players control the whole life of a stranger.
The rules of the game are very easy. All you have to do is choose actions that fit the character's age.
During the game, you'll have to take care of many different parts of your life. If your happiness falls below a certain amount, you will feel sad. If you eat badly and use drugs, your health can get worse to a very bad level. It's just like real life, but with a lot less risk. If you make good decisions, you can do well, but if you hurt people, you can go to jail.
Have fun and good luck!
