Everything in the frame - Age-appropriate puzzle fun with a base. 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. In addition, their hand-eye coordination and patience improve. Puzzles with the right level of difficulty allow children to grow with the challenge, boost their self-confidence, and most importantly, provide a lot of fun.
