Abstract: An intellectual knockdown maze including a plane seat board, several long and short side blocks with different lengths and four groups of L-shaped component blocks. The seat board is disposed with longitudinal and transverse partitioning lines which intersect each other at multiple intersections disposed with insertion holes. Each of the side block and L-shaped component block is formed with an insertion tenon on lower side for inserting into the insertion hole so as to locate the side blocks and component blocks on the seat board. The side blocks serve to form side walls of the maze and the component blocks serve to form partitioning walls of the maze. The lengths of the long and short side blocks are such that two long side blocks are arranged side by side along entire length of one side of the seat board to form a side wall of the maze, while a long side block and a short side block are arranged side by side along one side of the seat board to leave an entrance or an exit notch thereon.
