An intelligence jigsaw puzzle, comprising:

• a base partitioned by a flat plate;
• raised walls mounted respectively over and under the periphery edge of the flat plate for forming a holding chamber and a sunken chamber, the holding chamber and the sunken chamber being located independently;
• a plurality of buckling pillars mounted on a top surface of the flat plate, each buckling pillar being integrated with the top surface of the flat plate as a thumbtack;
• a plurality of jigsaw blocks located in the holding chamber, each jigsaw block comprising three obtuse arc-shaped apices;
• a cross-shaped notch formed on a top surface of the jigsaw block;
• and inward bended legs on a bottom surface of the jigsaw block;
• a top cover on which a plurality of pads are mounted;
• a filling block having a notch on a bottom surface;
• and
• an operation tool having a polyhedral head in which the filling block must be first taken away when the intelligence jigsaw puzzle is in use, and the three obtuse arc-shaped apices of the jigsaw block enable the operation tool to move the jigsaw blocks one by one for forming any pattern, geometric figure, or line.
