Christmas Wonderland 12 is a hidden object video game in which the player takes on the role of Santa Claus' helper. Christmas is just around the corner and Klaus and the elves are hastily preparing gifts for good children, but despite all the measures, they do not have time. Unless the protagonist gives them a helping hand, which will require visiting toy workshops, cities and other places. There you need to find lost gifts, missing parts of mechanisms, figurines of angels and other Christmas things. Then the holiday will be saved, and the kids will receive the toys of their dreams.

The game implements a special achievement system that marks the user's actions. If, for example, he can discover all the secrets on a level in a minimum amount of time, he will receive the corresponding achievement. These achievements are also earned by winning mini-games. Going through them is not always necessary for the plot, but the user thus gets the opportunity to test and hone their own skills. As a souvenir of completing Christmas Wonderland 12, the gamer can create photographs and store them in a special album.

If the user is tired of the main company, you can play additional modes. They are much more complex than the plot and can make even an experienced detective sweat. The puzzles in the project are varied – among them are both the standard search for similar objects and solving puzzles or riddles.
