How it works
- Enter your pieces. Choose your puzzle, then describe it: pieces to draw square by square, segments to count, or simply the date for the calendar puzzle. For pieces, a 3D drawing follows what you enter.
- Start solving. Emboîto looks for the solution in your browser and sends nothing. Solving can take up to a minute, and the page stays usable.
- Follow the assembly or print it. The assembly is animated in 3D, one step at a time, with its written sentence. You can also download the solution as a PDF to follow with the pieces in your hands.
