I'm in the library, and like other levels it has a mini game where you need to put something in columns in certain orders.
I hit HINT and it gave me on top "Volume" and on the side "Series". I don't understand what this game wants me to do. When I put something where I think it makes sense, it doesn't.
Please help me to understand this game, or even what pattern they want..its very frustrating.
Thanks! :)

In this mini-game the objective is to put the magazines in order to create a picture. Think of it as a large magines fold out cover. The magazine cover will contain a small portion of the next magazine.
For example, the travel magazine order is sail boat, palm trees, palm tree with camel, camel with pyramid and pyramid. Notice that the 2nd magazine had part of the water, the 3rd magazine had a palm leaf. The 4th magazine had another camel. The fifth magazine has a small piece of the pyramid.
 
If you need help with the other magazines let me know.
