The T column uses all seven Soma pieces, 27 cubes in total. Here is one solution: first the finished figure, then the pieces one by one from the floor up, in an order you can follow with real pieces.
- Vsmall corner
- LL shape
- TT shape
- Zstep (Z shape)
- Atwist A
- Btwist B
- Pbranch

Step by step
Build in this order from the floor up, lowering each piece from above. Every piece rests on the floor or on pieces already placed.
Step 1 · Place piece Z (step) on layer 1, at the back left. It lies flat as a zigzag from front to back: the front end is on the right, the back end on the left.
Step 2 · Place piece A (twist A) on layers 1–2, at the back right. Three of its cubes lie on layer 1, and one sticks up onto layer 2.
Step 3 · Place piece V (small corner) on layers 1–2, at the front. It stands upright like a wall running from front to back.
Step 4 · Place piece T (T shape) on layer 2, in the middle. It lies flat: a row of three from left to right, with the fourth cube sticking out to the front from the middle.
Step 5 · Place piece L (L shape) on layers 2–3, at the front. It stands upright like a wall running from front to back.
Step 6 · Place piece B (twist B) on layers 2–3, at the back right. Only one cube is on layer 2; the other three lie on layer 3.
Step 7 · Place piece P (branch) on layers 2–3, at the back left. Only one cube is on layer 2; the other three lie on layer 3. All 7 pieces are in place and the figure is finished.
Layer by layer, seen from above
Layer 1 is the floor. In each plan the top edge is the back of the figure and the bottom edge is the front.
Tip
Only pieces L and T can fill the cube at the front of layer 2. Try those there first.
About this figure
- Size: 3 wide, 5 deep and 3 high (in cubes).
- Solutions: 70 different ones. Counting every placement separately, including turned and mirrored copies of the same solution, there are 280.
- Counted with this tool's solver, which tries every position of every piece. Two solutions count as the same when turning or mirroring the whole figure turns one into the other (a mirror image swaps pieces A and B).
