The trickiest of our custom maze puzzles! Parts of the path are vision blocked by wood inserts in the dog body. There are a number of possible entrances and exits through these blocks, which is where the challenge arises.Puzzle measures about 7" x 7.5" x 3/4". It is both beautiful and durable made from floorboard material with an acrylic top. Balls used are standard BB's and we provide a small bag of about a dozen so you can have extras on hand.Artwork by Alexandra Plummer.Level of Difficulty: Level 4
