LÜK is THE learning game with independent control options. And the principle is very easy and identical for all three "boxes" from the bambinoLÜK to the classic 24er. Grab the corresponding LÜK control device and suitable exercise book and solve varied tasks tile by tile. A geometric pattern on the back shows whether everything has been solved correctly. And if not, the learners can correct themselves on a second attempt!
Lük is used by many schools and nurseries in Europe.
