You are working in a warehouse, where your job is to sort the crates to the places, where they belong to. First of all, the crates are heavy and pushing them requires huge amounts of strength. You can imagine how exhausting this can be when you are doing it all day long. Secondly, someone has messed up the placement of the crates. You must come up with a solution and sort them properly. One wrong move and you will have to start from scratch. Good luck and have fun!
