{"title":"Soma Cube Puzzles","description":"\u003cp\u003eThe Soma Cube is seven pieces made of unit cubes that assemble into a 3x3x3 block.

Shrinking Soma asks two at once. You need complete coverage of the opening AND a structure stable enough to survive shaking. That dual-condition requirement makes brute-force trial and error close to useless. You have to think about weight distribution, piece orientation, and structural integrity simultaneously - not just whether the geometry works out on paper. That changes everything about how you approach the solve.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eHow hard is Shrinking Soma?\u003c\/h3\u003e\u003cp\u003eExpert level - rated 4+ hours.
