Locked Bricks Construction Puzzle
The esteemed Locked Bricks Puzzle consists of 15 non-identical, interlocking wooden pieces. As is the case for most construction puzzles, the primary challenge is to find the technique required to unlock the bricks. Then, the real challenge is to rebuild the same shape that you just collapsed! The uniqueness of this puzzle is that the outward look of the shape is made of flat surfaces when the structure is put together, but the wooden bricks actually have zig-zagged grooves that mesh together during the building process.
