Things You'll Need:
- 1 classic 12-piece Kumiki-style cube puzzle
-
Step 1
If you have not already done this, take the cube apart. There should be two of each style of puzzle piece: two large, four medium and four small. Additionally there are two small pieces that have no match.
-
Step 2
Set the large pieces on a flat surface with the prongs pointing up. Take a small bar that looks like a flattened U and place it, prongs side up, into the groove of a large piece. Then take two of the medium-sized pieces and place them back to back on top of this, with their cutouts over the prong of the small piece. This combination of blocks will form an H.
-
Step 3
Set the second large piece on a flat surface with the prongs pointing up. Take the second small bar that looks like a flattened U and place it, prongs side up, into the groove of a large piece. Turn these two pieces over and place them on top of the H, aligning the small, flattened U-shaped pieces.
-
Step 4
Look at the cube from the side. There should be a hole in the center. Take the two small pieces that have a prong protruding from their center. Slide them into the center of the puzzle, one on the left, one on the right, with their flat sides out.
-
Step 5
Form two T shapes with the four remaining pieces. The Ts will be put in separately, one from the top and one from the bottom.
-
Step 6
Being careful to keep the center pieces together, turn the puzzle 90 degrees. Look inside the puzzle. You should see two holes. The T section with a gap will be placed first. Push the pieces in the cube aside to make room and insert the T, putting the medium-sized piece first. When the new pieces are in place, push all the pieces back into the cube.
-
Step 7
Turn the cube over and repeat step six with the remaining puzzle T piece.
