Picture of Snake Cube Puzzle Solution

The snake cube puzzle is a chain of 27 cubes (3x3x3). The cubes are interconnected by an elastic string running through the middle of each cube. Each section contains two or three cubes. The goal of the puzzle is to arrange the chain in such a way that there will be a 3x3x3 cube. It's not as easy as it looks.

I've included pictures for each step. You could also watch the video.

Step 1: Lay Out Flat - Look for This Section

Look for the sections that have 3 cubes next to each other. This is the starting point for the successful completion of the puzzle.

Step 2: First Move - Align the Two 3 Cube Sections

Flip the interior triple section as shown. They will now be alongside each other.

Step 3: Stand Up the Two 3 Cube Sections

Stand them upright where each end of the strands adjacent to the upright portion are on the table side (and not dangling in the air.)

Pretty easy from here. Its basically wrapping the strand around the core and filling in as you go.
