If you've been searching for a wooden puzzle that will genuinely test your patience and problem-solving skills, the Grandfather Burr is it. Designed by Dutch computer scientist W. L. Van der Poel, this 18-piece interlocking burr puzzle is one of the hardest in Kubiya Games' collection — and it earns that title honestly. It also makes a thoughtful, memorable gift for the puzzle enthusiast in your life.
✨ Features
- 🧩 18 Uniquely Notched Pieces: Every single piece has its own distinct notch pattern — no two are alike, which is a big part of what makes this puzzle so demanding.
- 🔲 Internal Gaps & Empty Space: The puzzle's structure includes deliberate gaps within its body, making it far less intuitive to visualise how the pieces connect.
- 🔐 Sequential Unlocking Mechanism: To disassemble the puzzle, you first need to find the precise sequence of moves that releases the first piece — only then will the rest follow.
- 🪵 Solid Wood Construction: Crafted from quality wood with a smooth finish, each piece has a satisfying weight and feel in your hands.
- 🎨 Display-Worthy Design: Once solved and reassembled, the Grandfather Burr sits beautifully on a bookshelf or coffee table as a conversation-starting art piece.
- 🏆 Expert-Level Difficulty: Rated among the hardest interlocking puzzles available — this is not a beginner's challenge.
