T Lock is a burr-style puzzle designed by Andrew Crowell and inspired from some of Chris Lowe's designs.
Andrew's goal was to design puzzles that had an incremental difficulty to them. The first piece comes out somewhat early in the solve, but it still requires more than 20 moves to fully disassemble after that first piece comes out. Rotations are allowed and encouraged.
T Lock will require 15 moves to free the first piece and 31 total moves to fully solve it.
The puzzle ships assembled. Disassembly is a bit of a challenge, but the real challenge will arrive when you try to reassemble it. Challenging but definitely possible without the help of a computer.
Andrew Crowell is an engineer by trade and enjoys puzzles. He makes precision wooden puzzles, and also creates 3D printed designs.
