How to build the Soma cube bottle

The bottle 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.

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.

  1. A

    Step 1 · Place piece A (twist A) on layers 1–2, at the front left. Three of its cubes lie on layer 1, and one sticks up onto layer 2.

  2. B

    Step 2 · Place piece B (twist B) on layers 1–2, at the back left. Two of its cubes are on layer 1 and two on layer 2.

  3. L

    Step 3 · Place piece L (L shape) on layers 1–3, at the front right. It stands upright like a wall running from left to right.

  4. Z

    Step 4 · Place piece Z (step) on layers 1–2, on the right. It stands upright like a wall running from front to back.

  5. P

    Step 5 · Place piece P (branch) on layers 2–3, at the back right. Three of its cubes lie on layer 2, and one sticks up onto layer 3.

  6. T

    Step 6 · Place piece T (T shape) on layers 3–4, in the middle. It stands upright like a wall running from left to right.

  7. V

    Step 7 · Place piece V (small corner) on layers 4–5, on the left. It stands upright like a wall running from left to right. 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 T and P can fill the cube in the middle of layer 3. Try those there first.
