  • Click on and item in the list and then click on hint if you need help.
  • You are given 3 hints for free at the start of the game and earn additional free hints periodically throughout your game.
  • There is a logbook kept in the game and at anytime if you aren’t sure what is going on be sure to read the logbook as it keeps track of everything you have done during the game as well as information that is required to solve mini game puzzles.
  • The game must be played in its entirety and you can access different areas of the game in any order you wish but you may not be allowed to progress until certain puzzles are completed.
  • As you play the game many of the items you find in the hidden object screens will go into an inventory item and must be used in other areas of the game. 
  • Many of the items in inventory must be combined before they can be used in a scene.
  • If you are lost in a scene keep your cursor at the bottom of the screen and back track until you find a familiar area.
  • The items in the hidden object screens may vary from the ones you see in your game as every game generates different hidden objects to find.
  • Most of the Mini games have the same solution and are included in the walkthrough where possible.  

Game Elements 
Game Icons/Cursors 


  • There are several icons to learn in this game and they are listed in the table above.
  • The "eye" icon means you can take a closer look either in or behind an item or it could be a hidden object scene or mini game.
  • The hand icon means you can grab an item and put it into your inventory in a scene.
  • The normal cursor is for normal navigation around the scenes.
  • The moving blue circles are "Areas of Interest" and if you see these click on them.
  • Arrows indicate pathways in which you can navigate around the game.
  • Mouse over the screen to look for arrows and ways to exit a scene. If in doubt mouse around the outer edges of the scene.  

Sample Hidden Object Scene 

  • This is an example of a hidden object scene in this game.
  • Note the items are in list form at the bottom of the scene.
  • There is an "Inventory tab at the bottom center where all of your inventory items are stored. You can access this at any time during the game.
  • You may hold items in inventory quite a while before you use them but they are all used within the same chapter they are introduced.
  • A. Logbook – This is where a log of all things in the game will be kept. You can access this at any time during the game. Important information is automatically stored here for you.
  • B. Hidden Object List – This is where all the items you are to find in a scene are listed. 
  • C. The tabs at the top are for you to access the inventory area and toggle between the inventory and list area.
  • D. Hint Buttons – Here is where you can see the silhouette of an item and click for a hint.  

Using the Hint Button 


  • Hints are located at the lower right of the screen in an instrument called a "Heliometer." 
  • Heliometer recharges hints and allows you to see the silhouette of any item you click on in the list of items you are to find.
  • You must choose an item in the list first by clicking on it and then click on hint and a sparkling graphic will appear around that item for a few moments.
  • Hints recharge and you are awarded hints periodically throughout the game.
  • You will be given 3 free hints at the start of the game and you can have a maximum of 4 hints at any time.
  • Mini-Games -Hints can be used in mini games and will either solve part of the puzzle for you or will solve the entire puzzle allowing you to skip it. There is no forewarning as to what a hint will do before you use it so be sure you are willing to skip a puzzle before you use a hint. 



  • Inventory items accumulate at the center bottom of the screen in the inventory area and if you have several items there you may scroll through it by clicking on either end of the inventory area.
  • If you see an item you would like to use in the game click on it and drag it to the desired location. If you are correct you will see the item incorporate into the scene immediately and if you are incorrect it will not let anything happen.
  • There is no penalty for incorrect guesses or random clicking in the game.
  • Many items in the inventory area must be combined before they can be used in a scene. 
  • Be mindful of items that are similar or that go together. If you can’t get something to work odds are you need to combine it with something else first.  



  • The logbook is located at the lower left of your screen and can be accessed at any time during the game.
  • After every scene the logbook is updated.
  • All critical information is kept in the logbook and you should refer to it frequently during the game. Especially if you are stuck.
  • The logbook is divided into 3 categories which are "Character Files" which keeps a picture and information about the characters you meet in the game. 
  • Click on the characters picture to read their biographical information.
  • The "Entries" portion is the journal portion and keeps track of all moves you have made in the game. 
  • The final category is "objectives" and this is the most useful part of the logbook as objectives are listed for you as you play along. If you become stuck this can guide you back on track but telling you what needs to be done in a given area.
  • There are detailed illustrations of machines in the logbook and this can be helpful in mini games.
  • Any time you need a code be sure to check your logbook as most of the codes used in the game are found there.  


  • This walkthrough will take you from start to finish.
  • The order the game is played in this walkthrough is one possible way the game can be played.
  • All areas must be completed before you proceed so the order is not critical to the outcome.
  • There are different hidden objects for you to find from game to game. The hidden objects in this walkthrough may or may not match the items you are asked for in your game but there will be many in common to help you along.
  • All the solutions to the puzzles and mini games are the same and are listed in this walkthrough.
