Triangle Ring 3 consists of 5 burr-style pieces that make up a total of 26 cubes that need to fit into the square shaped frame with two holes. Despite the seemingly large holes in the frame, there is only a single gap to allow the pieces to move once packed. The solution is an absolutely beautiful logical progression which you will only find by thought and not random movements. Made in a combination of either Maple & Mahogany wood or Wenge and Mahogany wood, this puzzle will be one you will surely need in your collection.
