Levels: levels are broken up into groups of three hidden object levels or scenes(referred to in the guide as scenes from left to right in your map tab), sometimes with one or two puzzles to solve either in-between or at the end of the three levels.

Blue Items: items in listed in blue can only be found by using an inventory item and may need to be saved for use in another area.

Note: these items may change in some scenes from game to game.

Professor's Journal: some levels will contain pieces of the Professor's Journal, if you see a small, paper icon next to the level image, it means their is a page hiding somewhere, I have circled these in Yellow (except for the 1st Casablanca level).

Find 20: some levels will require you to find 20 items, these are generally very easy, but the item to find will change from game to game, therefore there are no screen shots.
