Jinsei game is kiiiinda like sugoroku, but more complex! So like the name, you move through your life by going through the boxes. Every box has stuff like 'landing a big job, you get 500,000 yen!' or like, 'you got tricked, you lost 1,000,000 yen!'. You can get jobs, buy houses, have your own company, get money, stuff like that!
