Both games come from the 'Mystery Case Files' series, but offer self-contained scenarios and do not require knowledge of the other parts.
At the games is hidden object adventure that combine hidden object games with the adventure genre. It is progressing in the game by inserting objects in the right place. These items are obtained in part by dissolving Wimmelbilder. The puzzles are mostly logical; the objects in the picture are not too easy and not too difficult, but a few translation errors have crept in (fishscale is in this particular case no fish scale, but a fish scale), which make the image unsolvable. In such cases, the hint feature helps further that lets you display an object. In '13th Skull' you can also give general tips can be, so that this game plays fluid than 'Dire Grove', in which you sometimes do not know what you have to do next. The gameplay is interspersed with occasional Puzzle-tasks that can be but skip. All significant findings are automatically entered in a notebook so that you do not have to remember all the details.
Unfortunately missing in the two matches a card with fast travel feature, so you always have to run from one place to another. If you repeatedly find object A at one end of the game and the need to bring to location B at the other end, it is annoying. Also annoying is the background music in '13th Skull', which, although very well fits the Southern atmosphere, but is quickly unbearable. Especially bad is the in the finals, when one is regularly motivated by antagonists with always the same threats. In gameplay, it is annoying that you constantly get the task of collecting scattered for different people objects. Or twice to make inputs to the errand boy would be okay, unfortunately, this subject is far too used extensively. The idea to represent all the other characters with real actors is not well thought out. In this way you will feel transported back to the early days of the CD-ROM.
What the two games greatly enhances, the exciting and atmospheric stories that pull the player right in its spell. The surprising turn in '13th Skull' can even forget the logic error.
'Dire Grove' and '13th Skull' connect logical puzzles with a story that is so gripping that one for even the weaknesses mentioned in purchase takes, and thus belong to the league of hidden object adventure.
