Includes 15 different wooden pieces for making 120 puzzles of graded difficulty. Make the popular 3x3x3 Soma cube, the 4x4x4 Advanced Soma cube, towers, walls, animals, letters, numbers and other figures. Create your own figures and challenge others to make them. The puzzle is challenging, but not impossible, and with completion often in sight, you're not going to give up because success is always around the corner. The box is large enough to hold the pieces tidily without having to properly assemble the cube. This creative puzzle is made from white pine and/or birch grown in British Columbia, Canada. Due to the nature of the wood, color variations, knots and minor irregularities are to be expected, which will not detract from the enduring fun that this puzzle will provide.
