Frame puzzles are ideal for beginners due to the number and size of their pieces. The puzzle frame with the contour lines of the puzzle pieces facilitates the correct insertion and at the same time serves as a practical puzzle base, even on the move. Children train perception, short-term memory and logical thinking in a playful and fun way while puzzling. Besides, the eye-hand coordination and the patience improve as well. Puzzles with the right level of difficulty help the children to grow with the challenge, strengthen their self-confidence and, above all, are a lot of fun.
