A puzzle paper-block structure, which is made of a piece of paper having a given folding strength; the paper is folded symmetrically along a horizontal folding line, and then is folded further along a vertical folding line to form two sides (left and right sides); a symmetrical oblique folding line is used as a reference line to fold the left and right sides towards the vertical folding line; each side of the paper folded is folded into two fold sides (an inner and outer fold sides) along the oblique folding line; the inner and outer fold sides are folded together to form into an outer wing side; then, the outer end of the paper is folded along an inner-wing oblique folding line to have an outer fold side bent towards the inner triangle side to form into a symmetrical inner wing side. The inner wing side is then folded along the reference folding line to the outer wing side; then, the two outer wing sides are folded, along the vertical folding line, together to form into a triangle block unit; such a triangle block unit has a buffer area between the reference folding line of the two fold sides. After the triangle block unit is folded into form, the outer end angle becomes an inserting lug, and the inner and outer fold sides form into a lug hole. A plurality of block units can be assembled together by means of longitudinal and lateral connection to make various forms desired.
