It’s absolutely all of them, and more.
This game will give you a taste of how engineers manage and alter machine systems.
Start with Level One and complete One, Two and Three. Your teacher may get you to play through the first three levels as a group, otherwise complete them by yourself.
We cannot always predict the behaviour of a system purely based on a snapshot. Level Three is solved very differently once you see some parts are turning clockwise. We need to look closely and examine how the nodes interact within a system. Remember: nodes are parts that connect to each other to make up a system. If nodes are ‘things’, what nodes can you see in this game? (e.g. a cog)
