Machinarium

Make sure to scan the area for any object that you think you can pick up. It only takes a second to tap an object and see if Josef will snatch it for later.

You can get a full walkthrough for the puzzle you are on by tapping on the book. You will need to play a little mini-game to get the solution, but it is mercifully easy.

Remember that Josef needs to stand next to an object in order to interact with it.
