For the true lovers of Jigsaw Puzzles we have created the Hidden Puzzles category.
The previews of most puzzles are hidden as in your favourite monthly packs.
Each pack in this category contains some addictive quests for more challenge, for example, you need to complete the puzzle on certain difficulty to open the next image.
Please note that the level of difficulty and rotation mode in such puzzles can't be changed.
Just follow the hints!
There are currently 14 packs in that category so far, but we plan to add more in the future.
