I loved how Haym Introduced me to this design.
"SomaFours is my response to being annoyed that unlike all the other pieces one Soma Cube piece is made from 3 cubes rather than 4. So I replaced it with a 2x2x1 piece,. The puzzle comes with multiple challenges, including fitting them in a box with a restricted opening so that the extra cube sticks out a hole on the side plus making a cube that balances on the extra cube."
So there are two challenges here. Assemble the cube within the cage, which requires one piece to protrude through the side opening. The second, is to assemble the cube so that it balances one the protruding cube. This is the more challenging of the two in my opinion.
Two versions are available. I am also including a sheet that shows a few of the many shapes that can also be constructed with the new altered Soma. See how many new shapes you can come up with!
