Amazing Adventures 

This is a series of hidden object games for Windows/PC released by Popcap/Spintop games from 2007 to 2012. They were released via several platforms including individually sold CDs, and also on Steam and Big Fish Games. 

Gameplay is fairly basic and straightforward, and goes beyond basic find, point, and click. Bonus objects must also be found in each level scene (skulls, scarabs, gems, etc) to unlock the unlimited levels. Also, after each hidden object scene is another puzzle based on the next level which must be solved before progressing. This may be a jigsaw puzzle, a "spot the difference" puzzle, or "replace the missing objects" puzzle.

The Lost Tomb
Around The World
The Caribbean Secret
The Forgotten Dynasty
Riddle of the Two Knights

I've played all five of these, right through the unlimited levels, where they throw you everything they've got! In my opinion, these are an excellent balance of relaxation and challenge. I'm on the second time around playing them! To the best of my knowledge, this is the only complete collection of the PC games anywhere, even for sale. There is also one game released only for Nintendo DS, "The Forgotten Ruins", not included here.

Enjoy responsibly!
