Product Info

A ternary tile challenge by Andrew Parr.  Puzzle Master is the exclusive seller of his incredibly unique and attractive LEGO puzzle boxes!

The Twelve Puzzle is a sliding tile puzzle, inspired by the classic 15 puzzle. This puzzle has three separate challenges:

  • First, slide the tiles so the orange pieces form exactly seven complete circles.
  • Next, slide the tiles so the blue pieces form seven complete 2x2 squares.
  • Finally, find the arrangement of tiles so the green pieces form an unbroken circuit.

You can ignore the other colors as you work on each challenge. The circle and square challenges have unique solutions, while the circuit challenge has two possible solutions. Unlike classic sliding tile puzzles, this puzzle is built with tight tolerances. The pieces slide without twisting, resulting in very smooth and precise motion with just the right amount of resistance. This puzzle is very durable and the tiles will not fall out. The only rule is don't take any pieces apart!

Made using 353 LEGO pieces.
