The game is quite challenging, but not too heavy. In addition, you can set three different levels of difficulty. We have always played in the middle (default) level and - without us having to give the children their trains assistance - each solved task. Nevertheless, the motivation to play another round, always present; alone is to solve the next time the puzzle to an earlier "time". Especially if you play several rounds in succession, eventually enters the effect that one no longer knows whether the notice that as the apple of the tower is located, has now been put into this game, or the last. So I took the game over time rather heavier than lighter. To emphasize is the fact that you play together and at the end also together can feel like a winner - what we always resulted in a loud cheer.
We loved the game so much that we played there with four adults on a game night and thereby prompt that first time did not find the treasure (still in the middle stage - embarrassing, embarrassing!). So this is definitely not one of the games that are too easy, "if you have the hang of first out".
I also find the presentation of the game very well and also all the parts seem to be sufficiently robust.
Overall a clear recommendation!
