I have never heard of MiniLUK until we received it from our friends who went back to Germany as a birthday present for Anna. We didn’t give it to her then, because she had so many other presents, but we finally gave it to her now as an early Christmas present. It’s a learning game that is quite popular in Germany. First of all, you need a controller that you can see in the picture and can buy from Amazon here. By itself it’s a fun (and quite challenging) exercise for young children to put 12 plastic squares in proper places with proper rotation. Once the squares are in place, the game can start. To play the game, you also need special cards that come bound into a book. Ours were with instructions in German (and with some German words in some puzzles that are not needed to play a game successfully), but apparently you can also buy English books for different ages here. This is the most fun part about this whole concept, because cards can be made for any age. Our present came with three booklets – one for preschool with matching shapes, numbers and letters, another one is called “Kindergarten Olympics” with more challenging logical puzzles and yet another is “In the House” where the puzzles are mostly about matching parts to whole. My husband told me that he played with MiniLUK in teenage years as well, but the puzzles were a lot more challenging. The idea of the game is that one solves one square at a time (for example, finding a match between a shadow image on the bottom and the actual picture on top) and then places a proper plastic square to the transparent side of the controller. Once all 12 squares are matched, one can flip the controller, and self-check on the other side. If you solved it correctly, the color pieces on the other end will make some sort of a picture that is included on the side of the card. Interestingly, Anna first got the idea and played several games relatively easily, but as the puzzles got harder she started to fumble with the setup (which doesn’t change between games, it’s always the same) – it got too much for her. Note to myself – not to do more than 2 puzzles at a time, even if she wants to do more. I can see us buying more books in the future and also possibly making some homemade ones – it’s not impossible to do once you get several basic templates for self-checking.
