The Hidden Names are a list of names that are hidden in the puzzle. You can activate ‘Names Mode’ by tapping the word list under the current puzzle. This will indicate if there are any hidden names in the on-screen area of the puzzle, and allow you to select them in the grid. Tapping the word list area again returns to the normal puzzle-solving mode.

Note that some hidden names overlap multiple puzzle sections – you can scroll around the grid by pressing and holding until the ‘drag’ indicator appears.

You can view a list of all the names in the Info section (accessible from the Pause Menu).
