Soma Cube Challenge

Danish mathematician Piet Hein invented the soma cube in 1933 to distract himself during a lecture on quantum mechanics. Give yourself a similar distraction with this twist on a classic designed by Thai artisan Waraporn Khamsuk. While traditional soma games contain just seven pieces, the artisan designs this version with 25 geometric pieces. Carved from raintree wood, the object of this puzzle is to arrange the pieces to form a cube.
