Where does this corner belong? Do these puzzle pieces fit together? Frame puzzles are ideal for puzzle beginners due to the number and size of their pieces. The puzzle frame with the contour lines of the puzzle pieces makes it easier to place them correctly and also serves as a practical puzzle base, even on the go. While puzzling, children playfully and enjoyably train their perception, short-term memory, and logical thinking. Along the way, their hand-eye coordination and patience also improve. Puzzles with the appropriately chosen difficulty allow children to grow through the challenge, boost their self-confidence, and most importantly, provide a lot of fun.
