Puzzle Designers and Craftsmen

Logan Kleinwaks is a puzzle designer from the USA who has produced many fantastic looking interlocking burr puzzles. Logan has been designing puzzles since 2010, mainly of the interlocking variety, but also sliding block puzzles, puzzle boxes, pattern matching puzzles, packing puzzles, and a few strategy games. Logan tells us he would like to see happen/be a part of in the puzzle world:

1. Distributed computing effort to explore large puzzle spaces and find exceptionally difficult or interesting puzzles.

2. Small-scale puzzle production in one of the least developed countries in the world, with experienced puzzle designer providing designs to local craftsmen who could significantly increase their annual incomes by producing just a few puzzles per year. Designs would take into consideration the craftsmen’s skills, materials, and tools, so that, for example, high precision would not be required and there would be space for decorative embellishment in the local artistic tradition. Might partner with a local NGO to assist with disbursements of payments, export, quality control, etc.

3. Designing puzzles to aid research into mental benefits of puzzling, logical thinking, memory training, etc.

4. Collaborative design with other puzzle designers, especially with charity benefit puzzles.
