A few important reminders before anything else:
  • The items you need to look for in Hidden Object Scenes (HOS) are mostly random. I will, however, try to point out all of those in the list on the screen shot.
  • If you really can't find what you're looking for, there's a "Hint" button at the bottom right. It takes 1 minute for the Hint button to recharge.
  • The "Hint" button changes into a "Skip" icon for other puzzles. Clicking on "Skip" allows you to automatically solve the puzzle. It takes around 2 minutes for the Skip button to light up. 
  • On certain scenes, you will see Red/Brown sparkles. This means that you have to play the HOS. When you see Blue sparkles, it means there's a Puzzle waiting to be solved.
