It’s your retirement day and you have to train the newbies. And what do you do? Stand at conveyor and look for fault goods. If you find any just smash it with your hammer and slap the new guys when they sleep or poke into their nose.
The word simulation should be taken as exaggeration but this category is quite good for this game. Crash the fault things and watch the trainees if he is doing what he should. The goods change according the level you are in and some things are really hard to separate. Pleasant game with pleasant humor.
