To complete the Hidden Quest in Europe you just have to copy exactly the first 3 moves of your opponent who is either Emma or Hani. To do this watch their 3 first moves then do them yourself. If you try to do them when they are doing them you will get confused and do the wrong ones. You only have to do this on one board for one city and then you will be awarded the jewel.
I am on 58% and I have also completed the Silver, but Hidden is undiscovered and the Gold is still locked - these will only open up after you have done certain other countries and levels and the game will show which ones you can do after you complete every one.
Hope this helps.
I'm currently trying to complete the Hidden Quest in China but not having any luck although I am getting the monkeys locked in the cages without letting any monkeys escape the cities are not changing from blue to gold and I am not being awarded the jewel.
