Treasure chests puzzle locks
These puzzle locks will have different layers of difficulty which will be randomized between all the chests in the world. In this way you may find a difficult puzzle in the starter zone and an easy one in a lvl 80 zone
The rewards of these chests will vary depending on the puzzle difficulty but they wont be randomized. They will guarantee a reward consisting in a rare, exotic or ascended item.
I think this will bring a little bit more brain activity in the game.

I should add that these chests would be available once in a day.
Very good idea! It would be not just a chest locks, it would be a standalone mini games too. And not only 1, we would like more brain activity mini games.
brain activity: complex card game with Gw2 skills a very different mini game would be :
